I don't want to use more of your precious time, but just in case it triggers an idea - the sort order is fine but one odd thing is that the sub-questions (ie, answer options) are not in the lime_questions table, as others seem to, just lime_answers. They do appear when I edit them in the admin site.
That is default behavior.
