For most of those, the number is the day of the meet that the horse last ran (if it ran at OP).

Thanks for your reply! It's unfortunate for Oaklawn (and bettors) that they weren't able to draw larger fields for some of these races given the big purses they are offering. They attracted some quality horses for sure, but the small fields will negatively impact the money in the exotic pools.
