the Template::Iterator object sorts hashes by keys.  this is probably
what is causing unexpected behaviour with your presorted hash. perhaps
the hash should be explicitly sorted when passed to the Iterator.

something like:

          [% FOREACH item = hash.key_sort;
          	item.key; ": "; item.value;
             END %]

A 'value_sort' would also be handy for some types of labled data.
Just a thought.

    hugh.
