Obviously we can't report a credit score if the loan is in the name of a business, but if the loan is to an individual would we report the applicant's score that was pulled or report it as 8888 for not applicable since it's still a business transaction??

The only exemption for a credit score is when the applicant and co-applicant, if applicable, are not natural persons. Therefore, if your applicant is a natural person, you would need to list any credit score you relied on regardless of whether the loan is for business or consumer purposes.
