Issue Description:

Using a variable within an NBT tag does not appear to work correctly. Specifically, I am working on a script to add enchanted books up to "(Some Enchant) X" and am attempting to use a loop to reduce the amount of copy/pasta in my script. But attempting to use variables for either the level or enchantment ID results in an exception with the following message:

    Type 'java/lang/Short' (current frame, stack[11]) is not assignable to integer

What happens:

The script throws an exception while trying to create the NBT tag, and the item is not created.

What you expected to happen:

The NBT tag should be created using the values stored in the given variables, allowing the enchanted books to be added.

Try using a short[string] instead of a int[string]

Same result, unfortunately. Getting an error that Short can't be assigned to integer.

Tested around, a bit:

The issue is that Maps can't accept primitives, which is why ZS casts them as ther Wrapper type which isn't implemented that well into ZS.

This script ↓ works:

Alternatively, you could go for IData Maps, and use the asInt() where you need the integer. Added a working copy for that solution to the gist above
