Let me explain what I think is happening.
First, you seem to be double counting St. Michael's- as being on the maps and in G.V., but also as additional in the Valuation Books?
The town of Wexford contained five (5) historic urban civil parishes. That is, parishes located entirely within the town walls. From north to south, these were St. Selskar, St. Iberius, St. Patrick's, St. Mary's and St. Doologes. Almost by definition, these parishes did not extend out into the surrounding countryside - the town parks.
Outside the walls were three more parishes, St. John's, St. Peter's, and St. Michael's of Feagh. The town parks, surrounding Wexford, were located in these parishes.
Those of you who have looked at cancelled Valuation Office books for rural parishes will have noticed that they were at some point reorganized and rebound. You can see the trace of this in the page indexing of the townlands in the earlier books, which does not correspond to the actual page order. The original ordering was by civil parish. At some later point the books were changed to be organized by Electoral Division, and the earlier records were rebound and reorganized to reflect this.
But the valuation books for municipalites (towns) did not necessarily have the same organization. It seems that the cancelled Valuation Office books for Wexford town were reorganized on the basis of Wards, not Electoral Divisions. Wexford town was reincorporated in 1845, which appears to be the point at which the "modern" urban boundary was extended beyond the historic town wall limit, to include parts of the surrounding parishes.

Note that this change happened after the generation of the original 6" OSI maps, but before the publication of Griffith's Valuation. The later cancelled Valuation Office books, having been reorganized, reflect this change. The expanded town boundary is clearly marked on the 25" map on the Geohive site.
The newly expanded Wexford town was divided into multiple wards for electoral purposes. The wards - I think there were three? - were named after some of the original urban civil parishes. I know for certain that one was St. Selskar. I think a second was St. Mary's, not sure of the third (or more).
Within the town, the later (cancelled) Valuation office books are I believe organized by Ward. These wards extended beyond the original civil parishes of the same name, to include the newly incorporated surrounding land - the townlands. Thus, the Valuation Office books have some additional "townlands" - the parts of the original three Townpark townlands which were now within the boundaries of the wards comprising the expanded Wexford town.
One final note, however: I am not sure where all these changes left the original 1840s Valuation Office records, the ones created prior to the publication of Griffiths Valuation. It is these very early records which are available online!
Short summary: The boundaries of Wexford town changed (ca. 1845), between the generation of the 6" OSI maps (ca 1837-42), and the publication of Griffith's valuation in 1853. In addition, the expanded town was newly divided into wards, and later Valuation Office books were organized on the basis of these wards.
All clear?
