contact and interference

[Rbn3]

Runner on second with one out in a 14 year old tournament governed by "major league rules" except that sliding or "valid" attempt to avoid contact required by tournament rules. Ball is hit between second and first into right field. Throw to the plate beats runner who hits catcher shoulder first..catcher holds ball and runner at plate is called out. Batter/runner advances to second while cather (injured on the play) is on the ground.

What's the call, if any? Does "intent" of the runner hitting catcher matter?
