FWIW, I cannot reproduce it on a recent Org.

You could update Org.

I'm also surprised this doesn't work in Org 8.3.3, but my time machine
is being repaired at the moment, so there is nothing I can do about it.
Meanwhile, let me quote the usual licensing stuff, included in every Org
library (caps are not mine):

    ;; GNU Emacs is distributed in the hope that it will be useful,
    ;; but WITHOUT ANY WARRANTY; without even the implied warranty of

Again, I suggest to update Org. Release 8.3.3 is very old.
