ASA 8-7-P When, after bing declared out or after scoring, an offensive player interferes with a defensive player's opporutnity to make a play on another runner.
NOTE: A runner continuing to run and drawing a throw may be considered a form of interference. This does not apply to a batter runner who is entitile to run on the dropped third strike rule.


Based on your addition to the bottom of your plays, it appears the runner at 3rd never made an attempt to advance. If that is the case, what possible opportunity to make a play did the the runner advancing and the throw interfere with? As the note at the end of the rule states, a runner continuing to run may be a form of interference, not is interference.
