The $...$ construct is recognized by a regexp which, while complicated,
is not complicated enough to recognize everything that's marked
"punctuation" in the syntax tables. Look for org-latex-regexps in org.el
(and note that the regexp for "$" is about twice as long as the next
longest regexp - the one for "begin"). The others (for \(...\), \[...\]
and $$..$$) are fairly trivial.

Yes, probably - but looking at the regexp, I cringe: I don't want to even
try deciphering it, let alone change it - life's too short...

That is indeed the best solution.
