Someone has already pointed out that your item elements don't occur as
children of a data/item.

For a problem that involves sorting, then grouping, I recommend a two-phase
approach. Build a result tree fragment that contains the data in sorted
order, use the xx:node-set() extension function to convert this to a
node-set, and do the grouping in a second pass over this node-set.
