You can inspect the audio of a take directly with the audio accessor API. If you're good a scripting, it shouldn't be too hard to just grab the sample at the cursor and test its sign.

I just had a look at how stretch markers are stored in the project and I don't think it would be that hard to manipulate them...
Code:

The above shows an item with two manually added markers (in green) and the two item end markers automatically created by REAPER (in red). As you can see a marker definition is just two numbers, the first one the actual location, the second the original location, and the markers are separated by + signs. I don't think it would be very hard for someone familiar with python string manipulation to parse that info, change it and write it back to the item chunk.
