Most probably because no-one has reviewed it yet, but we can't say for sure, because we don't do site status checks here any more. Sorry. I'm just guessing on the basis that you say it is ecommerce. Shopping categories tend to be very popular with submitters, but much less so with editors.
If it is important to you to gain directory listings quickly, then I would suggest submitting to commercial directories, such as Yahoo!, where you can pay for rapid review.
