Well, I do something like that but using a manifest.scm file.

--8<---------------cut here---------------start------------->8---
$ cat manifest.scm
(use-modules (guix packages)
              (guix diagnostics)
              (guix))

(define pkgs
  (fold-packages (lambda (pkg lst)
                    (if (string-prefix? "guix-science"
                                        (location-file
                                         (package-location pkg)))
                        (cons pkg lst)
                        lst))
                  (quote ())))

(packages->manifest pkgs)

$ guix build -L ~/src/guix/guix-science -m manifest.scm -n
--8<---------------cut here---------------end--------------->8---


Hope that helps.
