It can never hurt to add it here, if it is a valid release. I have some albums showing up for me where the album name and order clearly came from me and my scrobbles. The syntax of them is not what MB shows and I had not conformed them to a standard format before they were scrobbled. These were added there prior to there change to perpetual beta.
Here is an example album: http://www.last.fm/music/Alexandra+Stan/Unlocked:+Deluxe+Edition
YOu can see on this one I am the only listener, at this time. You can also see that there are 2 others of the same name on the artist album page. Please note that what you stated is confirmed here, it does not appear on the artists albums page, but the album is there. I was not looking at it in that detail, just in the matter of getting the album recognized. As far as the album artist page, I would not know how they qualify to get there or not.
