I was able to get around this issue (and a couple of other font-lock related issues) by stepping back to an older version of Emacs (tag EMACS_23_2 in the git repository). I haven't tried to go back to the Emacs development HEAD, but I assume that they'll take care of this issue sooner or later, either way it's not a problem with any of the code in Org-mode.
