I strongly advise against using `org-next-item' in a defun. It is, in its actual form, meant for interactive use only. You should have a look at `org-get-next-item' and `org-get-previous-item' instead. I left a note about it at line 874 in org-list.el (yes, I know...). There is also `org-apply-on-list' that might be of some help.
