I don't know, whether they are not working, or whether you are expecing too much.

I didn't follow the discussion, when the overlay were introduced, but based on
my own observations, the overlays provide the following:
They give you an easy way, to create multiple Garmin-lines out of a single
OSM-way. But they do not help in changing the drawing order of the lines in the map.

I think, the drawing oder of the lines in a map can not be specified, but I
might be wrong and also my understanding of the overlays feature might be wrong.

If I want a line always drawn on top of another line, than I create a second
(and transparent) map layer with a higher draw priority for the upper line. For
the Garmin units both map layers can be combined into a single gmapsupp.img by
mkgmap and they are displayed fine. In Mapsource I haven't found a solution for
this problem, here I only know how to display one map layer at a time.
