I agree with Masi here. A customer as a property of a price seems a 
little bit awkward. I would implement it as a service, too.

$price = $priceService->getPriceFor($customer, $product);

Inside the Tx_Foo_Domain_Service_PriceService there could reside the 
logic resolving the price based on the properties of the customer ("gold 
membership").

You can check in the controller whether the customer is a logged-in 
frontend-user or not.

BTW nice UML diagrams ;-)
