They should be saying your bot doesn't count when touching the sidewall top wherever you go. It's in the rules!
SC 11 Each robot touching only the top of the center platform at the end of the match is worth
25 points. You are not fully on top of the platform if any part of a robot is touching any
part of:
- The ramp;
- The field;
- The top or outside of the platform/ramp structure sidewalls;
- Both of the inside platform/ramp structure sidewalls at the same time.
I think that is easy enough to interpret by anyone scoring matches.
