Is this a correctible error?

[JHut17]

The situation happened in a Rec league game goverened by NFHS rules. Team A was in the bonus. The scoreboard indicated Team A was in the bonus. The Lead Official called a foul on Team B, and the scorekeeper (a volunteer) did not provide any assitance to the official that Team A was in the bonus.
Neither Team's coach, or players, or the other official recognized Team A should be shooting the bonus. The Ball was put back into play and it was noticed about 10 seconds later that Team A should have been awarded the free throw. The Ref blew the whistle to stop play when the scorekeeper got his attention.
What's the correct ruling? 1. Should the ref continue play from that point awarding the ball to Team A?
2. Should the bonus be awarded to Team A?
