Try (in a shell) "id -a tim" and "id -a _spotlight" and see if you can
see any overlap.

Can you pick up the user name earlier on in the installer and pass it
onto your post-install script via some kind of variable?

You might get a more helpful answer on installer-dev, which I think is
the name for Apple's installer developer list.
