I looked at the code and I don't get what means the part of the code
getting the org-marker text property of a:
--8<---------------cut here---------------start------------->8---
(get-text-property (point-min) 'org-marker a)
--8<---------------cut here---------------end--------------->8---
In this part, the point-min returns the point-min of the current buffer
(the agenda buffer in that case) while the function looks for the
property into a.

I tried launching this code into a custom agenda compare function and I
get the error:
--8<---------------cut here---------------start------------->8---
Args out of range: 1197, 1197
--8<---------------cut here---------------end--------------->8---
This makes sense since the agenda appears to be narrowed at that time so
that (point-min) returns 1197 and the a string at this time is not 1197
characters long.

Replacing (point-min) by 0 appears to work (I assumed the 0th character
of the string has the wanted text property).

My first guess of an energy cmp function is:

--8<---------------cut here---------------start------------->8---
(defun org-energy-compare (a b)
  (let* (
		 (ma (or (get-text-property 0 'org-marker a)
				 (get-text-property 0 'org-hd-marker a)))
		 (mb (or (get-text-property 0 'org-marker b)
				 (get-text-property 0 'org-hd-marker b)))
		 (energy_a (org-entry-get ma "Energy"))
		 (energy_b (org-entry-get mb "Energy"))
		 )
	(cond
	 ((and
	   (not energy_a)
	   (not energy_b)
	   )
	  nil
	  )
	 ((and
	   energy_a
	   (not energy_b)
	   )
	  1
	  )
	 ((and
	   (not energy_a)
	   energy_b
	   )
	  -1
	  )
	 ((> energy_a energy_b)
	  1
	  )
	 ((< energy_a energy_b)
	  -1
	  )
	 (t
	  nil
	  )
	 )
	)
  )
--8<---------------cut here---------------end--------------->8---

Incidentally, I don't manage to have edebug triggered in a custom org
agenda cmp function. I load the function with C-u C-M-x. the message
"Edebug: org-energy-compare" appears as usual. When I launch the agenda
I can see the function has been called since the entries are correctly
sorted. But I was never given the input to debug it. Do you know why?
