The OP sent me a private reply, saying that he couldn't get it to work,
but he is using an old org version (whatever comes with emacs 24.3.1
IIRC, presumably pre-8.0).

I should have mentioned that I'm using fairly recent versions:

Org-mode version 8.3.3 (release_8.3.3-437-g4de71e)

on this machine and an even later one on the machine where I did the
above testing.
