Well, Hama didn't make any "bloodbending scrolls". She specifically said she'd not taught anyone else before Katara and was imprisoned after. I would have no problem if such scrolls existed, but they don't. Waterbending scrolls were used to teach commonly used forms to waterbenders. Bloodbending is not common nor is it an actual form. It is more of an understanding of the water in a person's body and how to control it. You could quite easily say he heard stories of Hama, Yakone, Tarrlok, and Noatak and that's why he wants to learn such things.
