random generator

Hello,

I used a random number script that defined a random variable, waited 15 seconds and then wrote it to a file. I had a very interesting result when I held down enter for a few seconds. Here is the code, then the results

code
#NoTrayIcon
$number=random(1,999999,0)
sleep(15000)
FileWrite("random.txt",$number&@crlf)
beep(1000,25)

now the results

notice, a 14 digit number. WHat are the odds of that coming out the same way more than 20 times. I was hoping someone could explain this to me. Are the scripts interfeering with each other somehow, using the same memory space or something?
