Yes, it does: the CC Mode shows the comment style in use and the minor
mode.

The sorting order was just one letter originally, so it sounds like a
good idea to have an indication of why the order is this and not
another.

Not IMO.  Using format strings and functions is "advanced usage",
which is normally barred for newbies and relatively inexperienced
Emacs users.  Popular options should IMO be exposed though easier
customization values.
