Oh, I see. I tested something way simpler :-)

First, one block to open and configure the guile session.

     #+begin_src scheme :session "!guile" :results silent
     (import (except (rnrs base) error vector-map)
              (only (guile)
                    lambda*
                    λ)
              ;; let-values
              (srfi srfi-11))
     #+end_src

Then, you can get to work and evaluate as many blocks as you like in
that session:

     #+begin_src scheme :session "!guile" :results output replace drawer :var x=1 :var y=2
     (let-values ([(a b) (values x y)])
        (simple-format #t "~a ~a\n" a b))
     #+end_src

     #+RESULTS:
     :results:
     1 2
     :end:
