I just attempted to contact the County Clerk of Tyler County, West Virginia for information about this through the email listed in the County Clerk Sections of the Official Election Results Secretary of State of West Virginia Website. Hopefully, this could help to determine what exactly happened.
For those wondering, I never got a reply on this email. To be honest, although I am still convinced that there is an error here, I will say that I can totally understand how the County Clerk might want to focus their attention to issues actually directly affecting the County today, whatever they are, over fixing an election result error from 23 years ago that has no real chance of actually doing much beyond slightly narrowing the statewide and national popular vote count, and of slightly changing the candidates number of Counties won.
