here is what upstream usually does:
1.0pre1 < 1.0rc1 < 1.0 < 1.0a
if the package manager doesn't know anything about what 'a', 'pre' or
'rc' means, you can't handle all the situations.
pacman (before the recent change, i haven't bisected it) handled pre/rc
properly and package maintainers had to do hacks for 1.0a-like releases
if we want to improve this, then probably the way to go is something
like what gentoo does:
they have regex like (alpha|beta|rc|pre|p)(\d*)$ and handle the
situation in such cases.
of course if you add such a complexity then you can say 1.0a is greater
than 1.0, and handle the prereleases manually.
