I've had a comparable situation come up where a player wanted to Stifle their opponent's Jace, the Mind Sculptor +2 ability to keep a particular card on top. The Jace player didn't give a moment for responses and just grabbed the top card. After ruling out cheating, it was a quick arrival to Looking at Extra Cards.

A player takes an action that may have enabled them to see the faces of cards in a deck that they were not entitled to see.
This penalty is applied only once if one or more cards are seen in the same action or sequence of actions.
As for the fix, there's to consider whether or not we shuffle away the scried cards. They were previously unknown to NAP. However, they weren't completely unknown and we want to follow through with the part of the fix that says “then put any known cards back in their correct locations.”
The Jace example above is perhaps more illustrative of the fact that we really don't want to shuffle away cards that one player knows about just because the other made a mistake and gained unnecessarily knowledge. We can't extract that knowledge from their head without also destroying knowledge for the other player.
You should shuffle the library, maintaining any scries including these ones. I thought about not bothering to shuffle, as it won't really change anything, although in this situation it protects us in case NAP saw the third card from the bottom. In the Jace situation, we did not shuffle and we were very sure no player had seen cards in the previously unknown portion of the library.
