I need a way to let users edit the delta of field-collection items without the use of the edit page

I'm using the eRecruiter profile and the Profile2 type Resume needs a way to let users reorder the education field which is a field-collection item. This can be done with the edit page (resume/%/edit) but not the resume view page which is what the user has access to. It is acceptable to add a weight field to each field collection form, but I'm not sure how to convert that weight to the field delta for each field collection item using a hook or a Rule.
