I tried (on Debian/bullseye with Emacs 29), but it doesn't seem to make
any difference here.  With or without the patch, I get:

larsi@xo:~/src/emacs/trunk$ emake; cat /tmp/script.el | ./src/emacs -Q --script /dev/stdin
Debugger entered--Lisp error: (file-missing "Cannot open load file" "No such file or directory" "/proc/162231/fd/pipe:[1065564]")
  load("/proc/162231/fd/pipe:[1065564]" nil t t)
  command-line-1(("-scriptload" "/dev/stdin"))
  command-line()
  normal-top-level()

Perhaps something further has changed in the meantime?  (You didn't post
an output of the error message you were getting...)
