That seems to work for me under MP2

My first guess is that it has to do with status renamings...

Instead of setting something to 200 / 500 , why not just set it to
the name of the status code, then use a Hash to pull out the
appropriate code for apache1/apache2?

personally i like 'human text' like that, then looking stuff up in a
hash of values when you need the integer code. it makes debugging
way less painful.
