Slightly refactor count resorting

The bug fix 8f043b2958477d3fe2ef094b7e42f792f4cf0b02 introduced a
secondary code path to trigger a resort of items. However, the previous
way to trigger it only required a small bug fix to work and gives us a
couple of optimisations for free. This commit removes the secondary code
path and fixes the primary one.
