Runner Hits Shortstop? What's the call?

[Paul L]

That's interference, immediate dead ball, interfering runner is out, all other runners return to base acquired at time of interference, batter is awarded first, and any runner forced by this award advances to the next base.

So assuming the runner from third had not crossed the plate by the time of the interference, this was not a wrong call.

Same for all rulesets of which I am aware, both softball and baseball.
