    Nope. You're using an array slice @x[$y] where you really want an element $x[$y]. And as pointed out elsewhere, you're using cmp where you want <=>.

    Thanks for the help. And now that I think about it, I probably should have got it on my own, but when I go into unchartered territory (functions that I have never used before), my brain freezes. Thanks again.

      if array#num is really a number, <=> might be a better option ... 
      @array = sort { $$a[2] <=> $$b[2] } @array;

    Thanks for the tip. I used this to sort my array[][][]. I was able to sort my list by an object property as follows: 
    @memory_blocks = sort {hex(${$b}[0][0]->address) <=> hex(${$a}[0][0]->
+address)} @memory_blocks;

    Hope that might help someone else who gets stuck. Thanks again!
