How to order images in a post in WordPress 3.3?

As far as I know, media management didn’t change from WP 3.2 to 3.3 (except for replacing the uploader itself with PLuploader). It has always been possible to upload images directly to the media manager (by uploading via Dashboard -> Media Library ), in which case such uploaded images would not be attached to any particular post.

To test that things are working properly, go to the edit post screen for a post that you know already has attached images, and verify that the media manager still displays the menu order field for the image gallery. Then, create a new post, upload some images, and again verify that the media manager still displays the menu order field.
