The quick hack would be to look in Template/Context.pm around line
596 for $list_ops and add your own sort function to the hash array.

e.g.
     'nsort' => sub { my $list = shift; [ sort { $a <=> $b } @$list ] },

       [% FOREACH order_number = order_record.keys.nsort %]

In version 2, it's $Template::Stash::LIST_OPS which you can set from
a script without needing to hack the source code.

     $Template::Stash::LIST_OPS->{ nsort } => sub { ... };

A numerical sort is probably worth adding as a permanent feature, 
so I'll probably squeeze it into version 2.  But there should probably 
be some better way to do this for the general case.


Hope this helps.
