Thanks for the nice description of the problem. I wouldn't mind if at
least a condensed version made its way into the commit message :)

I looked quickly at org-set-tags (and the functions it calls). Based on
commenting bits out, I think there are at least a couple of parts that
modify the buffer in a way that prevent save-excursion from restoring
the intended location. While not ideal, this after-the-fact adjustment
is probably the simplest way to deal with the issue.

Looks fine to me, with the minor nit that I think looking-at-p and
string-match-p would be preferable here.
Would you mind adding a regression test?
