How do Buppatsu and Ema score as a new Souvenir type?
They count as an extra Souvenir type, so they can fill a set slot like any other type and score 1, 3, 5, 7 or 9 points depending on how many different types are in that set. With one of each of the 5 types you reach 1+3+5+7+9 = 25 points. A card of a type already in a set starts a new set and is worth 1 point.
