Vanilla Item Sorting Priorities - tModLoader/tModLoader GitHub Wiki

When you use the sorting feature in storage (for example, sorting a chest), the items will be sorted based on their sorting priority in ItemID.Sets.SortingPriorityMaterials[]. When making a custom item, this value is set inside of SetStaticDefaults(), using ItemID.Sets.SortingPriorityMaterials[item.type] = XX (requires using Terraria.ID;).

For example, if you wanted your item to have the same sorting priority as a platinum bar (Item ID: 706), which has a sorting priority of 59, you would write this in SetStaticDefaults():

ItemID.Sets.SortingPriorityMaterials[item.type] = 59;

Here is a full list of vanilla sorting priorities, according to item ID (anything not on the list has a value of -1):
