How does the competitive scoring work?
Unless I missed something, there is no competitive scoring in it. They do spend about a page talking about how you can run the delves with a more board-gamey approach. As in: Forget about roleplaying and background, it's now you (DM) against them (players). Don't cheat, but do your best to kill them, using what is made available by the delve in question.
The suggestion is that while it doesn't give you the full D&D roleplaying experience, it can great to try once in a while, or for new DM's to learn the rules part of the game.
