OK, I'll have a closer look at which org-call-with-arg calls are
unnecessary.

True, at the very least, the prompt is confusingly phrased, but it's
probably an indication that the intended interface wasn't fully
implemented.

The interactive caller is certainly losing functionality, but my guess
was that sort-subr's default behavior is sufficient for handling the
keys returned by most custom key functions.  Probably a bad guess.
