12 and 13 are for counter control (documented in the type 1 supplement, 
Adobe technical specification 5015), 28 is a new one on me. I've seen it 
used but I do not think it is documented anywhere.

If its used in a multiple master, then it may simply be an Adobe 
convention, rather than an actual documented feature. Hardly anyone other 
than Adobe ever produced much in the way of MM fonts.
