Hi, r.param.scale should be the same in all the versions (and also manual pages are all the same). I don't know r.param.scale much but whenever I'm using it I getting almost no peaks. It looks similar to what is in the manual page -- almost everything on hills is ridge, just time to time there is a peak. Did you try playing with resolution (g.region res=)? If you are not satisfied with r.param.scale, in addons for GRASS 7 there is r.geomorphons, the results are usually very good if you play with parameters and resolution.
