At the moment there's no global way to cause tumblr posts to be tweeted (the API documentation both says that if send-to-twitter is omitted the post won't be tweeted, and on the other hand that it will be tweeted if the account is set to tweet by default; I've emailed tumblr support to ask about this). The second patch I've just added adds a --twitter flag that sets the send-to-twitter flag globally.
