It seems to work for now and is tight, took some effort to get them in but would like a more permanent solution. I do not know what happened as the inner part of the head tube does not look like it was reamed or enlarged from what I can see. Perhaps somehow flaring out that part of the cup so it would fit better. I have never run into this sort of thing before and of course I do not want to use anything that would make it very difficult or impossible to remove a cup.
I have never run into this sort of problem specifically, but have with the crown race on a fork (and a few other places like worn handlebars in stems that could never be tightened adequately). One solution that I came across (Sheldon Brown?) was to score the the steerer slightly with a hammer and chisel. The small nicks created a surface with small projections so that the race needed to be pressed on (albeit more easily than usual) and was held securely. I tried to make the nicks symmetrical. It worked well and I went touring with that bike.
Hope this helps.
