I posted this picture on your other thread a couple months ago. This shows the profile of the original weather stripping.(the one on the left) The style you have now is the style I'm going to use. Once installed, it will look close to original...I think. For all I know, the original part was rounded when new just like the repop.
The round section should be UP. The raised rib goes towards the inside on the original part. That's how I'd install the new one as well.
