Set::Scalar manages an unordered collection of values; it doesn't have anything corresponding to keys.

The simplest answer to what you seem to want would be a hash of arrays: 

my %data;

# create a key num_row with two values
@{$data{num_row}} = ( '12350', 'archive' );
# add another value
push @{$data{num_row}}, '613';

foreach my $key (keys %data) {
   print "Examining key $key\n";
   foreach my $val (@{$data{$key}}) {
       print "value: $val\n";
   }
}

print "num_row's 2nd value is $data{num_row}[1]\n";
