I get this:
Row 1 has an unknown In-App purchase price tier: 2.
How can this be an unknown price tier? I tried a few different ones like 3 and 4 but no go.
Also, on a related issue, there seems to be no way of getting the current price tiers into the Application Loader (the drop down is very very empty), so I can't actually edit/set the price tier for an IAP even manually using the Application Loader interface. Is AL heavily bugged?
