I foolishly installed Mavericks upon release and my Mac doesn't like it, so I used Internet recovery to downgrade to Lion. I am trying to get back to Mountain Lion but it does not seem possible anymore.
I know I could buy it again from here, but I don't want to pay for it again. I have checked the Purchases tab in the AppStore but it only lists Mavericks.
The only option I have left that I can think of is just torrenting it. This question may look like a duplicate. However, many of the questions are similar, and don't seem to address this issue.
Thanks for any help.

It seems that you bought Mountain Lion but now it has disappeared.
You can unhide purchases (some get hidden or you hid them, does not matter really) by opening Mac App Store.
Then go to: Store->View My Account->Enter AppleID and Password
There should be a "Manage"-Button for Hidden Purchases
Find OS X Mountain Lion and click "Unhide"
Afterwards Mountain Lion should show up in your Purchases Tab and you can reinstall.
