This isn't working for me if the main package and -selinux package are
in the same rpm transaction.

I have a set of packages on FC5 with this:

%post selinux
semodule -i %{_datadir}/selinux/packages/xpilotd/xpilotd.pp || :
/sbin/restorecon -R %{_bindir}/xpilot-ng-meta || :

The rpm transaction installs the -selinux subpackage first, which
installs the xpilot policy file which has a file context for
/usr/bin/xpilot-ng-meta.  But when rpm installs the main package next in
the transaction, the xpilot-ng-meta file does not get labelled correctly.

However, if I install these packages in separate transactions, then the
file gets labelled correctly regardless of which order the packages get
installed.  It almost seems as if the selinux policy does not really
take effect until after the rpm transaction has finished, even though
semodule -i was called in %post.

Adding 'Requires: %{name}' to the -selinux subpackage does seem to fix
the problem, however, as it seems to force the installation of the
-selinux package last, which relabels things correctly.
