Not very important gives an NPC 1 point, Important gives them 3, Very Important gives them 5 and Must Have means you won't find an NPC attractive if they don't have this trait. The same thing happens for turn offs except a deal breaker means that no matter how many other traits the NPC has that you like, they'll always be unattractive to your character.
From there, I think things are mostly still the same: Really hot NPCs have 4+ points, Cute has 2-3, mildly attractive only has 1, mildly unattractive has -1 point, not your type is -2 or -3, and really not your type is -4 or lower and/or has a dealbreaker
