I installed ConTeXt standalone and did the same thing as you, but with
tex related invocations, and I got this:

$ cat hello.lua
tex.sprint("Hello World")
tex.sprint("\bye")

$ mtxrun --script plain hello.lua
mtx-plain       | running command 'luatex --fmt=luatex-plain  "hello.lua"'
hello.lua:1: attempt to call field 'sprint' (a nil value)
