OK, projectile checks for the presence of *all* the files in the 
list. So there:

(defun projectile-dub-project-p ()
   "Check if a project contains a dub.json or dub.sdl file."
   (or (projectile-verify-file "dub.json")
       (projectile-verify-file "dub.sdl")))

(projectile-register-project-type
  'dub #'projectile-dub-project-p
  :compile "dub build"
  :test "dub test"
  :run "dub run")
