Adobe Distiller for Mac – PDF presets order in application

Hi,

I'm curious how to sort Adobe PDF presets (joboptions) in Adobe Distiller drop-down list. On Windows it is sorted alphabetically, but on Mac there is no obvious rule (at least for me) – it is not alphabetical nor date-based etc. If I rename preset file it mostly change its location in the list but again – it is not obvious why. Attached picture shows presets in folder and the list in Distiller.
