I really wouldn't mind which order it is put in, but I think showing both would be a significant improvement. Also a recognition of both in terms of free credits would give it some kind of official significance. Bear in mind that usually one alliance would win on both counts, and its victory would rightly be better recognised when judged on both criteria.
Edit: And total value, if not score as well, must be a simple total of members value. Regardless of whether they joined after leaving another alliance etc.
If you leave the score calculation as is, you might even get a funny situation where an alliance has more value than score
