How do we get the ball to tail away from the right handed hitter using an internal rotation delivery?

Assuming that your DD is a RHP and throwing a 4 seam IR 'fastball', more finger pressure on the index and middle fingers will cause the rotation to change from 12-6 to more of a 11-5 and will cause the ball to tail away from a RHB.

There are several threads which go more into detail.

This should probably be a complimentary pitch, as up and down movement is more effective than left to right as she gets older.

My DD naturally has this movement and she is still working on getting the ball to turn over more so she gets more downward movement.

My DD tails ball by applying more finger pressure on one side of the ball or the other.( Assuming your speaking of a fastball) So the finger or side she wants it to tail to she puts more pressure on that side and that finger comes off last. Whatever finger comes off last causes her ball to tail in or out on the batter.

Finger pressure will get some movement in either direction. She can also change her hand position at release and will likely get more movement. Turning the hand slightly so that the fingers are on the outside of the ball at release (thumb closer to the thigh) will result in movement towards the outside corner (to a R handed batter from a R handed pitcher). Fingers inside the ball (close to the thigh) will result in the opposite movement. Pair that with a peel drop release and you have some tough pitches to handle that don't really require trying to "spin" it differently.

A middle finger flick up the inside can also give you a curve/drop curve (see BoardMember’s corkscrew curve.) Neither give spectacular movement, but placed well, they can catch the inside corner or drift off the outside corner. Some kids throw these naturally and although I’d encourage kids to keep and refine the pitch, my preference is to master the drop, rise, change or offspeed drop.
