Could it be possible, that you get points for a challenge on the site
http://www.hacker.org/challenge/top.php even if you send a wrong answer? The number of solved challenges only increases if the answer is right, but the score increases also for wrong answers, when you try a challenge for the first time.

Yes, looks like that for me.
In
http://www.hacker.org/challenge/map/get.php you can see three possibilties for the solved parameter in the XML data:
- solved="1" (You solved the challenge)
- solved="0" (You tried and gave a wrong answer)
- solved="" (You never tried to give an answer to this challenge)
The number of points shown in the highscore is the sum over chal.difficulty**2 for every challenge chal with chal.solved != "".
