Maybe a bit late, but there's an issue in the OP's code that nobody else has explicitly mentioned, namely that the first line:

my @original_array = qw(5, 100, 2, 8, 40);

will actually put the commas in @original_array along with the numbers themselves, as would have been pointed out if -w had been on

In this instance, it doesn’t matter much, since if I understand correctly, perl will uncomplainingly do a numerical sort on strings as long as each begins with what it interprets as a number.

In other cases, however, putting unneeded commas in a qw(list) could lead to some surprises. Try this:

my @ary = qw ( 1, foo, 2, bar5, 33 );
for ( @ary ) {
   #print only the numbers:
   print if /^\d+$/
}
