Ah ha! Figured this out. I dug up the Windows Phone 7 API docs, and the legacy APIs actually still work on Windows Phone 8 as well.

public static void Session_PersistSession(string ticket)
{
   if (IsolatedStorageSettings.ApplicationSettings.Contains("SessionTicket"))
   {
      IsolatedStorageSettings.ApplicationSettings["SessionTicket"] = ticket;
   }
   else
   {
      IsolatedStorageSettings.ApplicationSettings.Add("SessionTicket", ticket);
   }

   IsolatedStorageSettings.ApplicationSettings.Save();
}

public static string Session_LoadSession()
{
   string ticket;
   if (IsolatedStorageSettings.ApplicationSettings.TryGetValue<String>("SessionTicket", out ticket))
   {
      return ticket;
   }

   return null;
}
