What I would do is make a custom vmethod in the calling perl script:
use Template ();
use Template::Stash ();
$Template::Stash::LIST_OPS->{'sortcn'} = sub {
my $list = shift;
@$list = sort { $a->{'cn'}->[0] cmp $b->{'cn'}->[0] } @$list;
return $list;
};
And then in the template: [% members.sortcn %]
Keep in mind, that will modify your original 'members' list.
Also, this is completely untested. If it breaks, feel free to keep both
parts. :-)
