It looks to me as if the zoom behavior can only be successfully applied when .hoverInfo is also present.
See http://vis.uell.net/mapmap/test_026.html as an example and comment out .hoverInfo
// .hoverInfo(['Ortsname','PKWDICHT2013'])
.applyBehavior(mapmap.behavior.zoom())
So non-thematic maps can't zoom (I know that's not the point of mapmap.js, but still).
