You should try calling validateNow() on the Label object.
Either that, or call your own invalidateDisplayList() and let
updateDisplayList() take care of triggering the effect.
public function set marqueeText(value:String):void
{
if (label.text != value) {
label.text = value;
invalidateDisplayList();
}
}
override protected function updateDisplayList(...):void
{
// do the effect here if necessary
}
