Data::Dumper is your friend. Here's what it gives me for your original code:

$VAR1 = [
          {
            '6' => 'Summary by Phase',
            'rpt_descr' => 'Summary by Segment',
            '3' => 'Cash Balance',
            '7' => 'Summary by Segment',
            '2' => 'QTD/PTD Financial Information',
            'rpt_no' => '7',
            '1' => 'Fiscal Year-to-Date Financial Information',
            '4' => 'Financial Status',
            '5' => 'Financial Summary Status'
          },
          $VAR1->[0],
          $VAR1->[0],
          $VAR1->[0],
          $VAR1->[0],
          $VAR1->[0],
          $VAR1->[0]
        ];

Not what you want!

By changing your loop to:

foreach $key ( sort keys %rpt_tbl ) {
    push( @radio_loop, +{ rpt_no => $key, rpt_descr => $rpt_tbl{ $key 
+} } );
}

It gives me:

$VAR1 = [
          {
            'rpt_descr' => 'Fiscal Year-to-Date Financial Information'
+,
            'rpt_no' => '1'
          },
          {
            'rpt_descr' => 'QTD/PTD Financial Information',
            'rpt_no' => '2'
          },
          {
            'rpt_descr' => 'Cash Balance',
            'rpt_no' => '3'
          },
          {
            'rpt_descr' => 'Financial Status',
            'rpt_no' => '4'
          },
          {
            'rpt_descr' => 'Financial Summary Status',
            'rpt_no' => '5'
          },
          {
            'rpt_descr' => 'Summary by Phase',
            'rpt_no' => '6'
          },
          {
            'rpt_descr' => 'Summary by Segment',
            'rpt_no' => '7'
          }
        ];
