It's been a while since this question was asked, but it raises some very important points:

The original app version field in the receipt corresponds to CFBundleVersion, not CFBundleShortVersionString. In a sandbox (developer build) environment, the value string is always "1.0".

Note that when converting from a paid app to freemium, if an original (paid version) user uninstalls the app, then reinstalls from iTunes, there will be no local receipt. Calling SKPaymentQueue restoreCompletedTransactions will not cause a new receipt to be downloaded if that user has never made an in-app purchase. In this situation, you need ask for a receipt refresh using SKReceiptRefreshRequest and not rely on restore functionality.
