Title: Sortable: Grouped items numbering

Ungrouped items seem to start at 0 whereas grouped items start at 1. i.e. in this example the top level (species) is an entity which doesn't have a field with a \SortableGroup and the second level (breed) does :

* Dogs (0)
* Greyhound (1)
* Bloodhound (2)
* Cats (1)
* Tabby (1)
* Siamese (2)

(This is my first ever attempt at a pull request so let me know if I've breached protocol or could have done something better)
