It should work reliably (but I couldn't find any links about it, besides Truth and Falsehood, Scalar values). You can force any true value to be 1 by adding !! before it. You can also use $r += $temp > 100 ? 250 : 0; if you are still in doubt.

Update: as pointed out above, it usually works and should work further, but the ternary operator is safer.

Sorry if my advice was wrong.
