You could also use the Sort::Fields module...
use strict;
use warnings;
use Sort::Fields;
use Data::Dumper;

my %hash = (
  "bill nye" => "39||Somehere in Cali||Cali||12345",
  "homer simpson" => "36||Springfield||unknown||23456",
  "barney rubble" => "31||Bedrock||cartoon location||3456",
);

my @sorted = map { /^([^\|]+)/ }
             fieldsort '||', [1, -1],
             map { $_ . '||' . $hash{$_} } keys %hash;

print Dumper(\@sorted);

And the output -
$VAR1 = [
          'barney rubble',
          'bill nye',
          'homer simpson'
        ];

 Update: just realized that solution will not work... doing soming debugging at the moment.
