Renderer.sortingOrder in Deferred mode

Hi!
I recently tried to switch the rendering path from Forward to Deferred and I was unpleasantly surprised that my solution for bullet wallmarks z-fighting is no more working. I used the sortingOrder renderer property increasing it with each new wallmark and it worked perfectly! But with the Deferred rendering path – the problem appeared again. Wallmark is just quad planes with Standard Shader material with Cutout rendering mode.
So the question is: is sorting supported in deferred mode and if yes, how to make it work?
Thanks!
