You can also acheive it, in a roundabout way, like so:
[% hash = { barney => 4, Wilma => 3, fred => 2, betty => 1 } %]
[% FOREACH n = hash.list.sort('value') -%]
* [% n.value %]: [% n.key %]
[% END %]
The "hash.list" part converts the hash into a list of hashes, each
having a 'key' and 'value' entry:
[ { key => 'barney', value => 4 }
{ key => 'Wilma', value => 3 }
{ key => 'fred', value => 2 }
{ key => 'betty', value => 1 } ]
Then the ".sort('value')" part sorts the list, using the 'value'
key to of each hash ref as the sort criteria.
