    Write a function that analyzes delivery route identifiers to determine how many characters in the tracking code appear in positions that match their natural sequence in the standard route classification system (A=1, B=2, etc.), regardless of letter case. This validation helps identify properly sequenced delivery routes in the fleet management system.
