I think, I figured it out myself:

python:

class ScrollPointTransition(Clutter.Transition):
    def __init__(self, from_point, to_point):
        Clutter.Transition.__init__(self)
        self.interval = Clutter.Interval(value_type=Clutter.Point, 
final=to_point)
        self.interval.set_initial(from_point)
        self.set_interval(self.interval)
        self.set_progress_mode(Clutter.AnimationMode.EASE_OUT_EXPO)

    def do_compute_value(self, animatable, interval, progress):
        point = interval.compute(progress)
        animatable.scroll_to_point(point)
