The downside of treating $ as punctuation is that $^2$ won't be
highlighted specially, but the upside is that "foo$bar" won't be
mishighlighted in a url.
To me the highlighting of math formulas is sufficiently secondary that
I'd err on the safe side (i.e. avoid mishighlighting). The other option
is to try and make this choice on a field-by-field basis, which seems
like a lot of work for fairly little benefit.
