The Empire's Throw Pulls Justin Turner Off the Bag

An official scorer of ours whom we've consulted before and asked him what he thought about this. He said due to the extraordinary effort of the shortstop they are going to say the throw pulled him off the bag had this been a more routine play at shortstop with this throw and foot pole. This is a very consistent scoring situation and would be scored in this manner every time I understand the point being made but this is how MLB applies it so he doesn't think there's anything fishy or unusual about this.
