Hurt is still an incarnation. The numbering doesn't make him an incarnation. Is the Master called the 1st Master? The 8th Master? No, he's just the Master. The Doctor is just the Doctor, but we call him by his regeneration numbers, 1 to 12, or the actor's name, to differentiate between them. There is no logic behind not counting Hurt.
