Follow-up: 

Here's what I implemented in 3.1.0-svn2708:

The version string has two parts: The version number, and the (optional)
version tag. The version number is a series of period-seperated nonnegative
integers. The version tag is of the form '-(svn|beta|rc)\d+'.

The higher-order parts of the version string are on the left. Version
numbers are ordered how you'd expect. E.g. 3.0.1 < 3.0.10 < 3.1.0.
Tags are significant only if two version strings have the same version
number.

Translate a tag into ingeters as folows: 

-    --> -1
svn  -->  0
beta -->  1
rc   -->  2
\d+  -->  itself

This ensures the following order: If two version have the same version
number, but one has a tag and the other doesn't, the tagless one is later;
and svn < beta < rc.

E.g.: 3.0.15 < 3.1.0-svn2708 < 3.1.0-beta1 < 3.1.0-rc3 < 3.1.0
