Minecraft Version: 1.7.10
Inventory Tweaks Version: 1.59-dev-152

I want to sort Custrom mods and added as example salt from PamsHarvestCraft:

I got the ID from NotEnoughItems, and no it dont have damage value

I tried also to replace the

with
(263 is correct id for coal)

As soon as I do, coal gets Sorten last as if ist a not knows Item
I did save the file, I dont get any error and the sorting work normal besides that.

Find the item's internal name (use F3+H with inventory tweaks installed in 1.7, it's vanilla in 1.8+)
