Got a hash like this 

$hash = {
k1 => [a1, b1, c1, d1],
k2 => [a2, b2, c2, d1],
k3 => [a3, b3, c3, d3]
k4 => [a4, b4, c4, d3]
}
For the arrays where the d's are equal i want to do a numerical compar
+ision on the a's and add a priority number at the end

The output i expect
$hash = {
k1 => [a1, b1, c1, d1, 1],
k2 => [a2, b2, c2, d1, 2],
k3 => [a3, b3, c3, d3, 2]
k4 => [a4, b4, c4, d3, 1]
}

#basically for k1 and k2 the d's are equal and a1>a2 so i added 1 and 2 respectively at the end and a4>a3 etc. I have a solution but wanted to know if anyone had a easier solution for this.(like a one or 2 liner) Thanks in advance.
