Sort returns the array sorted, it does not sort it in place. So just move your sort into the foreach

foreach my $line(sort @resultArray){

Now it uses the sorted array returned from the sort. Alternately you could modify your sort line to save that back into the orignal array.

@resultArray = sort { $a<=>$b } @resultArray;

Could anyone comment as to why sort doesn't do an inplace sort when called in void context?
