My tagging would be
tourist_bus=no (no private busses)
bus=no (no public transport buses)
school_bus=yes


+1


But "school_bus" is  used only a few times. The only thing I found is
http://wiki.openstreetmap.org/wiki/Proposed_features/access_restrictions_1.5, which proposes "school" as access tag for this, but this is not good either, as it may be interpreted as including private cars that carry children to school


+1, "school" is too generic, there isn't even a relation to access (could be used for school types etc.)


In my mind it should be
access:bus:school=*
because the namespace based structured approach would lead all taggers to build tags the same way naturally, without asking any such questions questions and replying +-1.
But I quit the idea after reading remarks such that the second word shouldn't be the determinant. Here, "bus" determines what kind of access it is and "school" determines what kind of "bus" it is. Some would have made it school:bus which is incoherent (preventing access to the schools that are buses) (1).
I had written a whole set of strict rules to propose and it's in the trash.

(1) OSM is unfortunately a place where you read an article about namespaces that does not specify the order of the names and tags such as "source=survey" that do not define what a survey is (my best notion of it is an e-mail questionnaire I reply to).
