There is a queryObj class with a setExpression() method that you should
be able to use.  However, I just realized that there is no way to access
existing query objects inside a layer from MapScript... you can only
create new ones.  This seems to be true with the Perl MapScript too, is
that possible, Steve?

Hummm... I guess this part of the code hasn't been used much before...
What you could do until this is resolved is not include a QUERY object
in your layer in the .map file, and instead create one in your script
using $query=ms_newQueryObj($layer); ... and then you should be able to
use setExpression() on the new object.
