This is the rule from the Bluenose Handbook :
4.4 11U A Only
A runner on 3rd base cannot score on a
pass ball or wild pitch. A runner on 3rd base cannot advance home
as a result of any interaction between the pitcher and the catcher.
In all cases where the pitcher pitches the ball to the catcher and there is a pass ball
or the catcher throws the ball back to the pitcher, regardless of the results of that
throw, No advancement shall be permitted from 3
From this I would conclude that the runner can score as the action was not passed
ball or interaction between pitcher and catcher.
