RPM just compares the versions-release per package name.  I'd have made the
same assumption on versioning. 8.1 is newer than 8.0.  Find the program
'rpmdev-vercmp', this will let you test out versions against each other so
you can see what its expected behavior is.  There isn't a lot of docs.  You
can jsut run the command and it will prompt you.  If you don't know what an
Epoch is you probably aren't using one and can just hit enter when prompted
for one.

rpm -ivh --oldpackage youpackage.rpm
