I don't think so. You cannot force inheritance for a special property,
which obey to its own rules. The optional argument is going to be
ignored. If the OP wants to get the SCHEDULED value of the current
headline or any of its parent, he can move up the hierarchy with
`org-up-heading-safe', calling `org-entry-get' at each stop.
