hmm, I updated (make update) after your fix, and I do see your commit in
the git history:

,----
| 2f359a6 * | ox-latex: Protect special characters in tags
`----

#+BEGIN_SRC emacs-lisp
 (call-interactively 'org-version)
#+END_SRC

#+results:
: Org-mode version 8.3beta (release_8.3beta-265-g7cf7e4 @ /usr/share/emacs/24.3/lisp/org/lisp/)

but I still see the very same problem, in my real world use case as
well as in the MWE. 

Maybe not yet fixed?
