How pick the item price from the list to which Customer is tagged on creating order.

A item can be tagged to multiple price list , so we want a extension that will pick or edit the item price as per the customer. For example, X Item is tagged to both B and C price list with different price and A customer is tagged to B price list , so when A customer comes to create the order and selects Item X than it should pick the price from the list to which customer A is tagged i.e, from B price list.
