I believe this is intentional. There are too many other uses of dollar
signs that people might want to use in Org documents that might be
broken if Org treated them as math mode delimiters; so the regexp that
matches math mode delimiters is deliberately limited in scope.
The recommended workaround is to use the \(...\) style of delimiter for
math mode instead, which is much less ambiguous. Here is a function that
makes this easy, by inserting these delimiters when you type "$". It's
been posted on this mailing list before, and I use a version of it
myself; it's very useful!

(defun yf/org-electric-dollar nil
"When called once, insert \\(\\) and leave point in between.
When called twice, replace the previously inserted \\(\\) by one $."
(interactive)
(if (and (looking-at "\\\\)") (looking-back "\\\\("))
(progn (delete-char 2)
(delete-char -2)
(insert "$"))
(insert "\\(\\)")
(backward-char 2)))
(define-key org-mode-map (kbd "$") 'yf/org-electric-dollar
Hope that helps!
