Noble Class: What ability scores?

[Hunteromega]

Hi, I decided to try the Noble class today but I noticed something: I have no idea what ability scores to give him, the class doesn't even have an entry in the manual.

Help, please?

Noble

(BASE CLASS)
Nobles are illustrious because of their rank, title, or birth. Nobles have the ability to use their background, education, natural carm, and skills in social maneuvering to their advantage in their day-to-day lives. An elven princess, the lord of Palanthas, a dwarven thane are all examples. While the motivations and goals of such characters vary widely, each is capable of masking his true intentions behind the veil of etiquette, and of using his charm and wit to gain what he desires.

It seems to be a warrior-type class with some party buffs. None of them depends on specific ability scores, so I would put all points into Strength or Dexterity just like with a fighter. I've never played that class though.
