It would depend on how much gear you ordered, and if they opened the package and saw it. From what I understand when Customs seizes a package they will notify local authorites and it would be up to them if they wanted to do a controled delivery. If you live in a low crime area your local cops might have the time on their hands to do this. This doesn't happen too often, and your chance of getting your gear are very good.
Now you might ask, "How much is too much to order?". That is the million-dollar question, nobody knows exactly. As a rule of thumb you want it to look like personal use, so you only want to order enough for personal use. It should be obvious to anyone looking at it that you didn't get it to distribute.
