Jetpack Shortcode Embeds

Hi! 🙂
Quick question: I’m using Jetpack and the feature to embed videos from YouTube/Vimeo & co with a short code (http://en.support.wordpress.com/videos/vimeo/).

For example on my website I added this code to embed a Vimeo video:
[vimeo http://vimeo.com/video_id w=200&h=150]

Everything works fine, except that I’d like to align the video to the left… I tried adding parameters like align=left, position=left et similia but it didn’t work..

Can you help me?

Thanks in advance,
Lorenzo

EDIT: Another thing I noticed (not really related to the topic but anyway a “MUST FIX”): the shortcode for Vimeo uses the old embed code. The new iframe embedder works for both Flash and non-flash browsers (iOS in primis), the old one doesn’t.
