Brother dsheroh has shown the correct comparison for the dataset you have provided. However, I agree with my fellow monk that the data structure is horrible. If I had to deal with this I would probably refactor it to be something more like `my $ArrayofHash = [ { name => 'TaskA', attrs => { 'maruti' => '20', 'honda' => '25', 'zen' => '25', 'hyundai' => '35', 'ford' => '22', 'toyota' => '11' } }, { name => 'TaskB', attrs => { 'maruti' => '11', 'honda' => '22', 'zen' => '33', 'hyundai' => '33', 'ford' => '24', 'toyota' => '16' } }, { name => 'TaskC', attrs => { 'maruti' => '12', 'honda' => '22', 'zen' => '33', 'hyundai' => '44', 'ford' => '55', 'toyota' => '66' } } ];` [download] This way all of your hashrefs have known keys so it's an easier comparison to codify. eg. `$a->{attrs}->{hyundai} <=> $b->{attrs}->{hyundai}` It depends on what your real dataset looks like whether or not this is an advisable approach.

my $ArrayofHash = [
          {
            name => 'TaskA',
            attrs => {
                                  'maruti' => '20',
                                  'honda' => '25',
                                  'zen' => '25',
                                  'hyundai' => '35',

                                  'maruti' => '11',
                                  'honda' => '22',
                                  'zen' => '33',
                                  'hyundai' => '33',
                                  'ford' => '24',
                                  'toyota' => '16'
                                }
          },
          {
            name => 'TaskC',
            attrs => {
                                  'maruti' => '12',
                                  'honda' => '22',
                                  'zen' => '33',
                                  'hyundai' => '44',
                                  'ford' => '55',
                                  'toyota' => '66'
                                }
          }
        ];

This way all of your hashrefs have known keys so it's an easier comparison to codify. eg. $a->{attrs}->{hyundai} <=> $b->{attrs}->{hyundai}

It depends on what your real dataset looks like whether or not this is an advisable approach.
