First, I would encourage you, and anyone else doing something like this
to strongly consider doing 'rpm -qf --qf "%{VERSION}"
/etc/redhat-release', as checking for the redhat-release package will
fail on RHEL.

Second, it shouldn't be a big deal to come up with a versioning scheme
that will satisfy your needs.  Epochs are definitely not the answer. 
Your best bet, if you require the new package to compare favorably
-18.rh80 would be to do -18.1fc, as that would be "newer" according to
rpm.  Recent rpm versions always will sort a numeric character higher
than an alphabetic character.

Thanks.
