I did not check why the other functions fail.
What about the following function? I'm on Org 9.
#v+
(defun mw-org-todo-with-other-date (date &optional arg)
"Like `org-todo' but ask for a specific DATE.
Optional argument ARG prefix arg."
(interactive (list (org-read-date) current-prefix-arg))
(let* ((org-use-effective-time t)
(hour
(truncate
(- (/ (org-time-stamp-to-now date t)
60 60))))
(org-extend-today-until (1+ hour)))
(org-todo arg)))
#v-
This function has been inspired by Org's `org-todo-yesterday'. The
latter even does its job when triggered from the agenda.
