Batter running outside first baseline to avoid tag with bases loaded

[toledotom46]

Bases loaded, 1 out, B1 hits slow roller toward first down the line, F3 charges ball looking for play at home, F3 fields ball fair just at the start of the running lane for B1 to run in, F3 instead of throwing home swipe tags at B1 running by, B1 steps out of running lane toward dugout to avoid tag, R3 slows coming to plate seeing no play and does not touch or cross plate before F3 swipes at B1, BU calls B1 out seeing his foot clearly out of running lane, but PU also calls B1 out for being tagged, Question: Does run count if B1 is called out for running outside running lane to avoid tag? Do runners all go back to previous base? Situation is ball becomes dead on avoided tag and runner not across home.
