here are some comments:
That goal should not have counted.
Assuming it was a goal kick, the Laws of the Game say "a goal may be scored directly from a goal kick, but only against the opposing team." If it was a direct free kick, the Laws of the Game say "if a direct free kick is kicked directly into the team's own goal, a corner kick is awarded to the opposing team."
Either way, that goal should not stand. Restart should be a corner kick since the ball left the penalty area and was thus in play. Had the wind turned it back before it left the area, it would be a re-kick.
