Are you sure that the scale points were assigned incorrectly? Because the way you're describing it is kind of impossible.
The refs that score scales happen immediately after the end of the match, but the ones that score red side don't even look at or score blue side, and vice versa.
I can't say for sure what happened, but I don't think they awarded your scale to another team without some very serious mistakes. It would involve a ref walking to the other end of the field to put in your scale on a different ref panel, then have that scale be corroborated by the other ref on that end of the field saying "yup, that scale happened"
