It looks like the 'check' phase ends with 'delete-file-recursively',
which has an unspecified return value, and that eventual failures from
'call-setuppy' are lost.

(define* (check #:key tests? test-target use-setuptools? #:allow-other-keys)
  "Run the test suite of a given Python package."
  (if tests?
      ;; Running `setup.py test` creates an additional .egg-info directory in
      ;; build/lib in some cases, e.g. if the source is in a sub-directory
      ;; (given with `package_dir`). This will by copied to the output, too,
      ;; so we need to remove.
      (let ((before (find-files "build" "\\.egg-info$" #:directories? #t)))
        (call-setuppy test-target '() use-setuptools?)
        (let* ((after (find-files "build" "\\.egg-info$" #:directories? #t))
               (inter (lset-difference eqv? after before)))
          (for-each delete-file-recursively inter)))
    #t))

Perhaps something like this would work (untested)?
