The key punch of the body number was a non integrated portion of the process so the body plate (trim Tag) could have a number wrong and the car's content still got entered correctly on other sections of the key card which are separate. IBM computer created the Broadcast sheet.

Key punch errors are the primary reasons that RPO content was missed at Fisher body.

Case in point; I know of a HO Z/28 built as an RS with all the RS Equipment that had X-77 on the body plate whereas the requirements for an X-33 build up on the body were carried out. I have known the car since a youth and the car has all right equipment for X-33 right down to the wiper motor.

incidentally that car is an 03-B build-pretty close to OP's car in a production time frame.

Same key puncher perhaps?
