I had this problem a few weeks ago, an app built for 10.9 didn't run on 10.7 (not surprisingly).
For a start try using the 'open' command to run the app from the command line, you might then get some error messages (or go look in the console to see if there were any).
Secondly - I put my deployment target back to 10.7 and it still didn't work .. because I was linking in one file from a library which was built for 10.9. Are you sure that everything is being compiled for a 10.7 deployment target?
Finally are you sure there's nothing in the app which actually needs anything after 10.7?

I have Mavericks, and his MBP is still on Lion. I didn't think this would be a problem, but to be safe, I set my deployment target to 10.7.My SDK is still 10.9, but I can only go back to 10.8 in my build settings, so I left that setting alone.

He unzipped it, double clicked the .app file… and nothing at all happened. No errors, no blank windows, it simply didn't open at all. I have an old Mini here that still has Lion, so I put the file on a thumb drive and tried to run it: same thing. Lion seems to not like this app at all, and I'm not sure why. After doing more googling, I suspect it is that SDK setting, but Xcode offers me no way to build for the 10.7 SDK, only 10.8 or 10.9
