See this VEX Forum thread:

Based on Q&A 809 (https://www.robotevents.com/VRC/2021-2022/QA/809)
And extrapolation of that "at the end of the match" ruling to all Mobile Goals in the Alliance Home Zone (in "Scoring Notes" on page 17, point 3)
It would seam that only Rings scored on or in the Alliance Mobile Goals will determine the autonomous winner.
Is that true?
