Do mobile goals on an alliance robot in their Alliance Home Zone count as scored? The only mention of transitive rules is in connection to the platform, and in the definitions the Alliance Home Zone is defined as the gray foam tiles themselves; it is not a 3-dimensional volume. This definition seems to suggest that only Mobile Goals touching a gray foam tile (or the Alliance Platform) count as scored.
The Q&A is closed for the 2021-2022 season. Any rule changes or clarifications pertaining to the 2022 VEX Robotics World Championship will be included in the April 5 Game Manual Update. Teams attending VEX Worlds who wish to pre-submit questions for the driver's meeting should have received a contact form via email; if not, please contact your REC Foundation Team Engagement Manager for more information.

804: Mobile Goals not touching tiles do not score?
This definition seems to suggest that only Mobile Goals touching a gray foam tile (or the Alliance Platform) count as scored.
This interpretation is correct.
Edit: In the v1.1 Game Manual Update, the definition of Alliance Home Zone was modified to include the following statement:
The Alliance Home Zones are a 3-dimensional volume, defined by the infinite upward projection from the foam tiles inside of the Alliance Home Zone boundaries.
Therefore, Mobile Goals which are being held by a Robot (off of the field tiles) would still meet this portion of the definition of Scored.
