C-h v completion-at-point-functions RET says:

,----
| completion-at-point-functions is a variable defined in `minibuffer.el'.
| Its value is (tags-completion-at-point-function)
| 
| 
|   This variable is potentially risky when used as a file local variable.
| 
| Documentation:
| Special hook to find the completion table for the thing at point.
| Each function on this hook is called in turns without any argument and should
| return either nil to mean that it is not applicable at point,
| or a function of no argument to perform completion (discouraged),
| or a list of the form (START END COLLECTION &rest PROPS) where
|  START and END delimit the entity to complete and should include point,
|  COLLECTION is the completion table to use to complete it, and
|  PROPS is a property list for additional information.
| Currently supported properties are:
|  `:predicate'           a predicate that completion candidates need to satisfy.
|  `:annotation-function' the value to use for `completion-annotate-function'.

so it's an emacs thing, not an org thing. You can try loading minibuffer.elc but
it is rather surprising that it's not there already. Unless it's an emacs23 vs emacs24
thing - I run emacs24 and it's present there, but I just tried emacs23 and it does not
seem to be there even after I load-library minibuffer.el.
