Nobody knows on earth if you don't know. s(x,r,t) would not be a TRUE function if it range space is not well defined.

The classification is based on how the quantity transforms under a change of coordinates. If it is invariant then it is a scalar (strictly speaking) but sometimes people call any quantity which can be expressed by a single number as a scalar which is not correct usage.
