Adding Experience Tools to Turtles Doesn't Work Correctly

[Flexico]

I'm using a data pack to allow turtle to wield a number of tools from mods, like gem tools from Bluepower, but the Experience Tools from Create Stuff Additions don't drop experience points when they dig blocks like they do when I use them as a player!

Here's the code that lets the turtles equip them:
{
  "type": "computercraft:tool",
  "item": "create_stuff_additions:experience_pickaxe"
}
