Accounts may not be displayed in order of account number.

[jrick]

The Wallet model class uses a Dictionary keyed by Account (numbers) to store account properties. When used as an IEnumerable, the order is not defined. This can cause the ObservableCollection of recent accounts in the shell view model (which does have an ordering) to order the accounts in an implementation dependent manner.

I think the best way to solve this issue is to maintain a sorted List of accounts and their properties in the Wallet class. Other than the imported account (which is planned to be removed from btcwallet in a later update), all accounts numbers are strictly increasing.
