The decision to have the type 3's considered should rest on your small business portfolio. If your numbers are strong there is no need to consider reviewing (and doing additional data integrity) on these deals. If you post weak figures and using the type 3's as additional support would help, well then by all means do your homework and include them.
Type 3's are not going to be the major determining factor in an exam though. You're much better off spending time mining your portfolio for CD deals than spending time on the type 3's in my opinion. They just aren't of enough value in comparison.
You mentioned determining if these were CD. I would highly doubt that you're going to have much success qualifying this type of deal as a CD loan unless you've got a real doozie of a deal out there. Again, spend time on the bigger deals and save these for desperate times

When desperate measures become more important to your survival.
