Thanks, Rasmus (and Marcin), replacing the $ by \( and \) works.  I
didn’t know about the parentheses notation.  To my experience most
people use the $ notation for inline math, and therefore it would make
sense to properly support that notation, too.  Especially since it used
to work in earlier versions of org (if I’m not mistaken) and there is
nothing in the manual suggesting that it shouldn’t work.  The contrary
is the case.  Quote from the manual:

  To avoid conflicts with currency specifications, single ‘$’ characters
  are only recognized as math delimiters if the enclosed text contains
  at most two line breaks, is directly attached to the ‘$’ characters
  with no whitespace in between, and if the closing ‘$’ is followed by
  whitespace, punctuation or a dash.

Parentheses are punctuation, so the $ in my example should be
interpreted as math delimiters.  I think whoever wrote the code, simply
overlooked parentheses when implementing the punctuation part.  This
should be fixed.
