This came up in a newsgroup but there was only one person responding who would only repeat himself regardless of what was posted. I'm looking for more insight into how people read this regarding scalars.
In Geoetricaal methods of mathematical physics by Bernard F. Schutz the author defines "scalar" as follows. From page 64
Consider the 4-momentum P and the particular basis vector e_0. Do you hold that P*e_0 is a scalar? Yes or no answers prefered.

In Geoetricaal methods of mathematical physics by Bernard F. Schutz the author defines "scalar" as follows. From page 64
A scalar is defined as a (0 0) tensor,, i.e. a function on the manifold whose definition does not depend on the choice of any particular basis.
Consider the 4-momentum P and the particular basis vector e_0. Do you hold that P*e_0 is a scalar? Yes or no answers prefered.
