Org-mode sets org-font-lock-keywords while the mode is turned
on, locally in each org-mode buffer, because depending on setup,
the keywords can be different in different buffers.

Please take a look at the function org-set-font-lock-defaults,
and in particular use the hook org-font-lock-set-keywords-hook
in order to append your stuff to the variable
org-font-lock-keywords-extra (no, I do not know why
it is called extra - I must have had a reason for it once :-) )
