I'm not sure what you want to point out with that link. I know there are scripts there, but that doesn't change my opinion that it's not the best space for scripts to begin with. HTML::Template can also be found on freshmeat. Not the best place IMHO.
Most scripts can benefit from putting the functionality within a module. In that case, you're distributing the module and the script comes along with it. cpan, pod2html, and many others most people take for granted fall into this category.
Easier to test because you're testing a module
Easier to reuse in many scripts
Easier to subclass for other people
My criteria for good software:
Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
