Here's your problem --- you're setting up MyTreeModelSort with the  
interface and all that good stuff, but in the constructor, you're  
creating a TreeModelSort, *not* a MyTreeModelSort.

*Reblessing does *not* work with Glib::Object::Subclass!*

Your new() should look like this:

   sub new
   {
      my ($proto, $childModel) = @_;
      my $class = ref($proto) || $proto;
      return Glib::Object::new ($class, model => $childModel);
   }
