Quincey alluded to that,

In other words, it will run in Lion and Mountain Lion. But if Apple decides to remove the 32-bit system libraries in, say, Mac OS X 10.9, then your app will not run in 10.9.
An app can be converted to 64-bit, if you've got the source to all of libraries, but it is not any fun. I just finished converting a large app with a lot of old code. This app was mostly 64-bit already, because at least I'd started using NSInteger and friends a few years ago when I dropped support for 10.4. But it still took me 5 days with BBEdit to examine all of the changes produced by Apple's CocoaConvert64 tool, and it was so boring that I kept wanting to run outside and chop wood. Converting a large app that has not been touched in many years as you've described will require membership in a good fitness center, and major psychotherapy.
