try:

$class->setexpression("([COST] < $maximum)");

setexpression receives a string. PHP's strings in betweeen '' are 
textually evaluated (ie no variable substitution occurs), so you
need to put those "" around it or use the . operator.

btw, the '' are not needed by mapserver, i have
this line :

$class->setexpression("($str)");

and works fine.
