[nitems] returns the total number of items in the cart, whereas the
[item-*] tags refer to a particular item in the cart and are intended
for use within a container such as [item-list].

Try this as a test:

[item-list]
    Discount for [item-quantity] of item [item-increment] is
    [mix-sale-off number="[item-quantity]" prodformat="[item-modifier formats]"]
    <br>
[/item-list]

I assume that you are happy to modify the values in your UserTag
whenever your price/discount structure changes.  Why not just use
CommonAdjust and a pricing table to calculate your format prices
and quantity discounts?
