Score the run

soundedlikeastrike,

This is the best I could find. Reading this, I would uphold the 4th out and not allow the run, using the second part of 7.10(d) listed below. The 4th out "takes precedence," thereby not allowing the run to score.

OBR 7.10(b):
Any runner shall be called out, on appeal, when—
With the ball in play, while advancing or returning to a base, he fails to touch each base in order before he, or a missed base, is tagged.

OBR 7.10(d):
Any appeal under this rule must be made before the next pitch, or any play or attempted play. If the violation occurs during a play which ends a half-inning, the appeal must be made before the defensive team leaves the field.

Appeal plays may require an umpire to recognize an apparent “fourth out.” If the third out is made during a play in which an appeal play is sustained on another runner, the appeal play decision takes precedence in determining the out.
