Description:
------------
The sorting on the statistics page is inconsistent with the main module page, and does not follow either the release date or the version number. It appears to do a standard string sort on the version number, which is inappropriate.

Expected result:
----------------
I expect a sort that either orders correctly by version number, or by release date, both of which would be more readable.

3.1.2  	beta  	2008-12-12  	APC-3.1.2.tgz
3.1.1 	beta 	2008-12-12 	APC-3.1.1.tgz 
3.0.19 	stable 	2008-05-15 	APC-3.0.19.tgz 
3.0.18 	stable 	2008-03-28 	APC-3.0.18.tgz 
....
3.0.10  stable  2006-03-11  	APC-3.0.10.tgz
3.0.9 	stable 	2006-03-04 	APC-3.0.9.tgz

Actual result:
--------------
I get the sorting visible on this page:
http://pecl.php.net/package-stats.php?pid=220&rid=&cid=3
