I am having a little trouble with sorting a hash of hashes of an array. I needed to print out the data sorted by the value of a certain array element that is contained in a hash that is contained in another hash. I was able to get the result I was looking for but I know there must be a better or at least a more perlish way of doing it. The actual data structure is much larger than it appears below but the following code is sufficient to describe the issue. Any ideas would be greatly appreciated. 
#!/usr/bin/perl

use strict;

my %hash;

$hash{cust1}{current}[0] = 13;
$hash{cust2}{current}[0] = 110;
$hash{cust3}{current}[0] = 10;
$hash{cust4}{current}[0] = 102;
$hash{cust5}{current}[0] = 108;
$hash{cust6}{current}[0] = 130;
$hash{cust7}{current}[0] = 10;
$hash{cust8}{current}[0] = 107;
$hash{cust9}{current}[0] = 5;
$hash{cust10}{current}[0] = 210;
$hash{cust11}{current}[0] = 1;
$hash{cust12}{current}[0] = 160;
$hash{cust13}{current}[0] = 16;

my @sorted;
for my $x(keys %hash)
{
    push @sorted, "$hash{$x}{current}[0]|$x";
}

for my $x(sort sort_num @sorted)
{
    my @key = split(/\|/,$x);
    print "$key[1] - $hash{$key[1]}{current}[0]\n";
}

exit;

sub sort_num
{
    return $a <=> $b;
}
