You can use the custom function in the sort command to supply org-sort
with a random number. When calling org-sort, note the function option
presented:
,[ C-c ^ (org-sort)
| Sort %s: [a]lpha [n]umeric [p]riority p[r]operty todo[o]rder [f]unc
| [t]ime [s]cheduled [d]eadline [c]reated
| A/N/T/S/D/C/P/O/F means reversed:
`
You could thus write a quick function, using whatever amount of
randomness you want:
--8<---cut here---start->8---
(defun my-org-random-sort ()
(random 1000))
--8<---cut here---end--->8---
Then on the appropriate subtree/table/list, type:
C-c ^ f my-org-random-sort

Sorry this response comes a little to late. :)
