I'm getting the same as you with your MWE.
   
The tag, used by ob-comint async, is:

   "/tmp/babel-zqh04P/python-GL5N5d"
   
but, in "/tmp/bug.org" it becomes:

   "babel-zqh04P/python-GL5N5d"

(`org-babel-result-to-file' transformed it into a simpler relative
path).

The filter `org-babel-comint-async-filter' cannot spot it, because
it's searching for the exact string "/tmp/babel-zqh04P/python-tXsdFw".

Here is how to reproduce:
   #+begin_src elisp :results table
     (let* ((tag "/tmp/babel-zqh04P/python-tXsdFw")
            (repro 
             (lambda (fn)
               (let ((lnk 
                      (with-temp-buffer
                        (org-mode)
                        (let* ((default-directory "/tmp")
                               (buffer-file-name  fn)
                               (cbuf (clone-indirect-buffer "tmp" nil)))
                          (with-current-buffer cbuf
                            (org-babel-result-to-file tag))))))
                 (list fn
                       (not (eq nil (string-match-p (regexp-quote tag) lnk)))
                       lnk)))))
       (cons (list "Filename" "string-match-p" "Org link")
             (cons 'hline
                   (mapcar repro (list "/tmp/bug.org" 
                                       "/somewhere/else/bug.org")))))
   #+end_src

   #+RESULTS:
   | Filename                | match-p | Org link                               
       |
   
|-------------------------+---------+-----------------------------------------------|
   | /tmp/bug.org            | nil     | [[file:babel-zqh04P/python-tXsdFw]]    
       |
   | /somewhere/else/bug.org | t       | 
[[file:../../tmp/babel-zqh04P/python-tXsdFw]] |


I don't know what a proper fix would be though.
   
Hoping this help,

Bruno
