Hmm, very wierd, maybe they choosed a behaviour like that to make it easier in comparisons.

so 1 will be true in every condition, and false will have an empty string as output, so it will always result in a false.

actually to get the 0-1 way, just use intval($val==intval($val)); that should return what you want.

edit: vb2.2 isn't compatible to the newest default settings of php, as php doesn't interpolate that much as php4 does.
so you need a better coding to run things in php5. Some settings can be set so it acts like php4 in a lot of ways, but not on every aspect i think.
