Scheduling App Store Downloads

Hello.

Unfortunately, I have limited wireless access - 10 GB a month with unlimited downloading between 2-8 AM. I was wondering if there was a way for me to schedule my downloads on the mac app store between those times?

From what I can tell, the apps continue to dl even after the Mac App Store has been closed. Any apple scripts or anything I can use to automatically resume downloads. I don't want to have to stay up half the night everytime I want to download a large file.

Thanks for your help.
