Thus, I think that my website is correct in sorting the version numbers. 1.2 should be later than 1.18. I think your versioning system is wrong ;-)
Ok as this is not *my* versioning system, I will explain. I use CVS, and extract version from something like:
$VERSION = ('$Revision: 1.18 $ ' =~ /(\d+\.\d+)/)[0];
I don't remember where I see this first time.
But after a google search, it seems I must do in fact:
$VERSION = sprintf("%d.%02d", q$Revision ... $);
