Very likely if you edit the submission you can put it back. HN strips several things from submissions, including leading numbers, and obvious swear words. This helps prevent the most crude forms of spamming, but you can go through the effort of editing the title to restore most of them.

Think of it as a kind of CAPTCHA.

Edit: But it's too late now, you needed to do it in the 2 hour editing window.
