error?

[Cordileran]

This is more a scoring thing than an officiating note, but I'd like to hear your opinions. This happened in a South Atlantic League single A game tonight. No one on, batter hits a ball to the shortstop and is running hard to beat the throw. The shortstop throws it away from the first baseman, but the runner, running hard, runs over first base without touching it. On a perfect bounce of the fence the first baseman retrieves the ball and tags out the runner. The scorer had an error on the play even though the runner never legally acquired first base. Your thoughts?
