My two cents: I think simplest way to say it is: if you pulled and other team pushed the solar panel you should have received 22 points and they 40.
Totally possible refs missed it. E.g. not related to Solar, but in ours once they missed we had the gas core and once missed we did food production. (And overall I think our volunteer refs were great - they graciously changed the sheet when it was pointed out to them).
Hate to waste learning time having the kids practicing to make sure they understand the scoring sheet [though we spent plenty of learning time having them practice the robot runs], but handling potential errors is a good way for them to learn respectful communication [and not a bad lesson to make sure they completely understand something before signing it].
