I've not heard of it not working. Got a link?
Got any more details on what's "not working"? Sample code snippet etc?

You need to adjust the center of the scaling to suit the group's transformation, and of course the scaling itself in case the group itself is scaled ?
If the group is made at the origin and there's no further transformations then it should be very simple ?

Important note: If you apply a transformation to entities that are not in the current edit context (i.e. faces that are inside a group), SketchUp will apply the transformation incorrectly, since the geometry has one origin and the current edit context has another. You can correct for this by watching the Model.edit_transform and Model.active_path. See ModelObserver.onActivePathChanged for more information.

I put it in the origin and tried, there still is a problem ,the side face of the tube come out of the group(component) with the top and bottom face being still in the group
