The problem is that org-mode assumes that planning line must be a single
line and a lot of internal logic hard-code this assumption.

For example, below is a fragment of org-get-property-block:

     ;; Move point to its position according to its positional rules.
     (cond ((org-before-first-heading-p)
	    (while (and (org-at-comment-p) (bolp)) (forward-line)))
	   (t (forward-line)
	      (when (looking-at-p org-planning-line-re) (forward-line))))

The last line clearly assumes that planning line is always a single
line. The same assumption is made in many other places in org-mode
internals. Though one may write a patch to make multi-line sexps work in
org-mode, there is also a problem with external tools working with org.
I do not think there is support of multi-line planning everywhere.

You can always use file-local definition at the beginning or end of your
org file. Below is an example of local definition at the end of an org
file. 

# Local Variables:
# eval: (defun your-function () (sexp))
