    Given a list of user interaction scores from a social network, determine how many potential friend pairs would be compatible based on their social compatibility metric. Two users are considered compatible when the XOR of their interaction scores yields an even number, indicating similar social patterns and mutual interests. Write a function that returns the total count of such compatible user pairs from the given interaction scores list.
