I believe this is very close but the problem now is my new hash, "$value_hash", can only hold one unique key. Therefore if I have list of values like: 
colour  device   value
----------------------
red     bike      1000
red     shoes     1000
blue    car       4
black   plane     6
blue    boat      1000
pink    shoes     5
red     car       5

The $value_hash will only have the following list: 
colour    device   value
------------------------
blue      boat     1000
black     plane    6
red       car      5
blue      car      4

A hashes' keys must be unique, otherwise they get over written with the most recent entry. To prevent losing data, incase I have count values which are duplicates, I recreate a new hash with 3 keys and a value. The keys are "value", "colour", and "device". Creating New Hash "value_hash" (2nd hash): 
foreach my $colour ( keys %hash) {
        foreach my $device ( keys %{$hash{$colour}})
        {
                my $val = $hash{$colour}{$device}[0];
                $value_hash{$val}{$colour}{$device}[0]++;
        }
}

After that I then print the key (value) in order: 
for my $value (sort {$b <=> $a} keys %value_hash)  {
        for my $colour ( keys %{$value_hash{$value}})  {
                for my $os ( keys %{$value_hash {$value}{$colour}})  {
                        printf("\n%-55s %-50s %-10s",
                        $colour, $os, $value);
                }
        }
}

Which now produces table... 
colour  device   value
----------------------
red     bike      1000
red     shoes     1000
blue    boat      1000
black   plane     6
pink    shoes     5
red     car       5
blue    car       4

Thank you for pointing me in the right direction monks...Papai
