I think this is a valid critique of the title. Sorting means whatever it means in a specific context (dewey decimal system, post addresses, etc...).

Most languages are context sensitives, but generalized computing is fundamentally defined by a context free language in which a processing transition can execute and not care was previous states were. This gets blurry with recursion and generics and other syntactic sugar, but fundamentally state changes are still defined by the operation and instantaneous state and not the language itself.

So in our context-free language of generalized computers, sorting and ordering are the same.
