That shouldn't be too hard.  Have a look at `tags-search'.  That sets
`tags-loop-scan' to `(re-search-forward ',regexp nil t) to do the actual
search.  So just make your own `lars/tags-search' function by copying
`tags-search' and setting `tags-loop-scan' to something like

  `(when (re-search-forward ',regexp nil t)
     (check-whatever-needs-to-be-checked))
