Numerification of Order:: constants

[Reed, Mark \(TBS\)]

S03, lines 418-420:  "[cmp] always returns C<Order::Increase>,
C<Order::Same>, or C<Order::Decrease> (which numerify to -1, 0, or +1)."
 
Shouldn't Order::Increase numerify to +1 and Order::Decrease to -1?  In
which case it would be clearer to put them in respective order above...
