This is really, really strange. I can't explain what happened.
I just run #5 now again on fresh kernel, with M 9.01 and now it gives a result !
I really do not know why and how this has happened. You saw the output and that it did not evaluate before.
This means M has 10/10 score now (but I do not do penalties for non-elementary anti-derivatives and for long computation time, so Albert's more advanced scoring scheme will give different rankings)
