hi

i thought i've found someting in the archiv, but this won't work for me, because all of the hashes have different keys i don't care about

i want the array to evolve from this:
%{array[0]} = { key1 => 1, key2 => 4 };
%{array[1]} = { key3 => 8, key4 => 4, key5 => 6 };
%{array[2]} = { key6 => 3 };

to this: 
%{array[0]} = { key6 => 3 };
%{array[1]} = { key3 => 8, key4 => 1, key5 => 6 };
%{array[2]} = { key1 => 1, key2 => 24 };

well, it works with this:
sub SortArrayOfHashes 
{
    my @array = @{(shift)} ;
    my %valuesum;
    foreach my $i (0 .. $#array) {
        my $sum = 0;
        $sum += $_ foreach (values %{$array[$i]});
        $valuesum{$i} = $sum;
    }

    my @sortedarray;
    foreach ( sort {$valuesum{$a} <=> $valuesum{$b} } keys %valuesum )
+ {
        push (@sortedarray, $array[$_]);
    }

    return @sortedarray;
}

but i believe there must be an easier way
any ideas how to optimize this?
