okay, i really have to look a little bit deeper into the topic, could you point out those that look overdone?
I think this is a good chance to look a bit into individual tastes, monitor dependency and different sharpening scripts.
Just look for contrast halos. Dark-ish tree or horizon edge against bright-ish sky... Zoom up a little and notice a 2 or 3 pixel hard halo. When you see that (or when others notice it) is makes them think the images are over-sharpened... Although that's pretty much exactly what you want for prints. 
The other tell-tale feature is granulated shrubbery. This is also due to the hard halos but it's not necessarily seen as a hard line and appears to most viewers as granulation. Like someone sprinkled colored sugar over the texture or something.
If it's only the the horizon lines or a simplistic tree with external border halos (as opposed to the inner halo granulation) you can often just use the smudge tool in darken or lighten (as required) to eliminate them. Of course it's better to use a sharpening plug-in that doesn't cause them in the first place.
If you don't wanna be bothered using plug-ins one method that works a little better than usual is to convert the image to Lab color space, select only the grey channel, turn on the "Lab" eye so you're seeing color, and then use "Smart Sharpen" until you get the desired amount. After you get the right amount I would recommend running the Fade tool and lowering it to about 80% or 75%. The conversion, selection, Color view, Smart Sharpen (w/ GUI), and Fade (w/ GUI) can all be put into your script. The GUI makes those steps interactive too - so you can tune for each image only adding a few seconds to the processing times.
