Pause for a few sections? or conditional wait?

So i have a rule that when I download a .nzb it opens it up and starts my download. I also have a rule that when a file is downloaded to my desktop it sorts it into a folder.
The problem is that these two rules both at the same time.
Is there a way to pause a rule for 10 seconds, or a few seconds? that way I can have my sorting rule wait a certain time for a file to be on the desktop, then it will process it.
since the desktop is a holding pen for alot of stuff, I use it alot. (import to itunes, nzb download, etc)
Would this be something found inside a script? like a shell script etc, or is this built in, or is there any other suggestions.
Thanks
