I'd like correct a detail:
the current order is core, site, vendor, obsolete dirs.

What you call "rest of site" are previous incarnations of sitelib,
implemented using otherlibdirs.
1) /usr/local/{lib,%{_lib}}/perl5/site_perl
- These two (they are one on 32 bit archs) are to be removed soon
  (F-11), they were present only for a limited transition period.
2) /usr/lib/perl5/site_perl
- It has been promised that this obsolete sitelib will stay
  permanently, and that there will be no others to join it (see
  bz 484053).

I agree that "site, vendor, core" seems sane.  A quick check on a
Debian installation with perl-5.8.8 seems to indicate that they share
this idea.

More poking shows that the change was implemented on Fedora by
perl-5.8.5-incorder.patch.  Version up to 5.8.5 and including some of
the releases of 5.8.5 followed the upstream order which always has
been  "core, site, vendor"

During the update to 5.10.0, this patch has been dropped, perhaps
unintentionally.

I've yet to check whether the patch is still present in latest Debian
builds; if yes, I'm all for including it again.

Have a nice day,
