I don't think there's anything built in for this, but you could just
override your ResultSet search and insert a default order_by into the 
attribute hash if one doesn't already exist.

Yep - see the docs for DBIx::Class::CDBICompat - you want ColumnGroups,
which allows:

  __PACKAGE__->columns(menu => qw/foo bar/);
