Any method to sort customfieldset positions?


Can’t seem to find anything in the shopware docs, about ordering the different customfieldset in the right order.

I have a demo shop where i have the sample data aswell, so predefined customfieldset is Electronics, Kids, Shoes, Music.

I just created a new called Custom Description, and that is put just in the middle of the reset, so the lineup is Electronics, Kids, Custom Description, Shoes, Music… 
so i really need someway to sort the custom fieldset order, anyone got an idea for this problem? you looking at a shopware noob :) 

Each field has an position index, have you tried to use that ?
