I see what you mean. Yes, that is a problem: see below for a fix.
The reason you confused me is that this doesn't affect "Select
Enclosing Brackets", which I don't think uses the scope information
at all. Indeed, "Select Enclosing Brackets" works perfectly as expected
in all the cases I've tested, including the one you just posted.

You *can* see the problem by typing

  {$foo}

positioning the cursor after it, and pressing control-shift-P. This shows
that
the brace group is still in effect. The fix is to use a lookahead:

        …
        {    name = 'string.other.math.tex';
            begin = '\$';
            end = '(?=\})|\$';
        …

Thanks for pointing this out.
