My attempt at getting the highest score

[pavned]

That Arnold Heningem is so good to get XP, too bad I didn't knew that before killing him. Would have save him for later and use an AK on him!

Not sure about the numbers but I think I got more then 10k XP from him without AK on (but Shark, Memoirs, 1 hand and level 2 learning). He kept summoning Demon Portal and getting Demons which, themselves, kept summoning demons. I think at one point there was 13-14 ennemy stacks on the field! Counting that I was facing him with only my stack of 3 Red Dragons, it was a great XP generating battle.
