(guix scripts …) *is* the command line interface, so it makes sense,
that its interface handles command line arguments.

launch-environment/container still assumes the command to be a shell
script, which I think is not quite what you want.  You probably want to
take a look at call-with-container from (guix build linux-container) or
child-hurds.
I currently don't know of any procedure, that "directly" invokes Scheme
code through Guix environments, so you'd have to build that on your
own.  However, given that your stated goal is to port container entry
scripts [I read this as "the script called by the container at entry"]
to Guile, would it not make sense to have

  (guix-environment [ENVIRONMENT OPTIONS] "--" "guile" "entry.scm")

WDYT?
