I would assume that the Customer has used the story's overall worth to determine whether the project is worth continuing (or even starting). You are right that sorting stories only provides relative value. If the team costs $50k/iteration and the team is only doing about $35k of expected net revenue/iteration, then it's time to stop the project. 

In XP: The Customer needs to make those calculations as a way to decide whether to continue the project.

Not in XP: Which calculations to make and how.
