How about this:

  (use-modules (gnu packages)
               (guix build-system pyproject)
               (guix build-system python)
               (guix packages))

  (fold-packages (lambda (pkg count)
                   (+ 1 count))
                 0
                 #:select?
                 (lambda (pkg)
                   (and (not (hidden-package? pkg))
                        (member (package-build-system pkg)
                                (list pyproject-build-system
                                      python-build-system)))))

For me, this returns "2749".
