What you describe is, IMO, a "school sponsored activity".

also... PC seems clear about school vehicles.

PC §46.03. PLACES WEAPONS PROHIBITED.
........
(1) on the physical premises of a school or educational institution, any grounds or building on which an activity sponsored by a school or educational institution is being conducted, or a passenger transportation vehicle of a school or educational institution, whether the school or educational institution is public or private, unless pursuant to written regulations or written authorization of the institution;

Emphasis mine.

School sponsored activity is irrelevant to this discussion. As Charles has outlined in one of the earlier TFC podcasts, including the written authorization phrase in the statute limits the scope of "school sponsored activities" to only those grounds that are part of the school campus or property. A principle can't authorize the carrying of a handgun on property that the school doesn't own or control. Otherwise, you'd have to leave McDonald's when the high school football team shows up if you are carrying.

To address the OP's initial question - refer to school/district policy. If they allow concealed carry in district vehicles or while on district business, then you'd be ok to carry. If policy forbids it, you could be disciplined or fired for carrying. But you wouldn't run afoul of state law.
