IMHO, Code is the right place for this; and within that, PerlMonks Related Scripts is nearly spot on. However, it would be nice to separate code (or "code") used on the site from code used for accessing the site; so IMHO a new Code sub-section would be in order.

Clearly, editing the Code sub-section pages needs to be opened up... but I'm not sure a new group is needed for this; surely one of janitors, SiteDocClan or pedagogues could be appropriate...
