interesting. I don't know about an existing module, but here are some ideas for your search algorithm:
Assuming you want x number of elements in array that add up to y 
sub searchLoop {
- pass in:
  - target number (y)
  - number of elements desired (x)
  - the array (array)
  - y offset number (offset, starts at 0)
- sort array in descending numerical order and store that into a tempo
+rary array that you can mess with.
- remove entries in the temp array that are larger than y
- foreach ( unshift a value off temp array into z) remaining entry:
  - if z = y, print z+offset as a solution (or return it if you only n
+eed one solution)
  - run searchLoop(y-z, x-1, temp (with the z element removed), offset
++z)
}

This is a very rough sketch, but it should get you started.
