With this ^^^ your additional paths are "shadowed" by the default
value of 'tramp-remote-path'.  Try to make it reverse:

   (setq tramp-remote-path
         (append '("~/.guix-profile/bin" "~/.guix-profile/sbin"
                   "/run/current-system/profile/bin"
                   "/run/current-system/profile/sbin")
                 tramp-remote-path))

However I don't think you need to set all these paths manually.

The different behavior between 0.12 and 0.13 may be caused by this
commit:

  http://git.savannah.gnu.org/cgit/guix.git/commit/?id=dc7010911dd3285fe9089352e92c77501595d100

i.e. your problem may occur because 'tramp-default-remote-path' is the
first element of 'tramp-remote-path' variable now.

I don't know if it will help you or not, but here is the setting I have
in my emacs config, which works for me for years:

(with-eval-after-load 'tramp-sh
  (push 'tramp-own-remote-path tramp-remote-path))
