i have the following code:

use strict;
use Data::Dumper;

my $market_hash;
my $name = "a";
my $i = 0;
my $sort_by = 111;

for($i = 0;$i<15;$i++) {
   
    my @test;
    my $whatever = "sadfa";

    push(@test, $whatever);
    push(@test, $whatever);
    push(@test, $sort_by);
   
   
    $market_hash->{$name} = \@test;
   
    $name .= "a";
    $sort_by--;
}


print &Dumper($market_hash);



foreach  my $market (sort { $market_hash->{$a}[2] cmp $market_hash->{$
+b}[2]
 } keys (%{$market_hash}) ) {
    print "$market ---------------- $market_hash->{$market}[2]\n";
}
