That's a known issue when a mod is unpublished, but actually the ratings are not lost, they reappear when a new rating is made, as I have now done on your mod.
EDIT: This should now be fixed, though this is a difficult fix to verify, as I would have to catch a mod, that had visible ratings before being unpublished, that has been unpublished, then fixed by its author, and catch it to see that it still has visible ratings before anyone updates the ratings again. So for this one I'm just assuming the fix should work.
