actionscript algorithm

im trying to find the most occurring element in an array, but im trying to be clever about it instead of doing the long as sub-array method my class is doing currently

i cant tell why this isnt working

int cmp(const void * a, const void * b){
  return *(int*)a - *(int*)b;
}

why?
