Just finished with updated version of Ext.ux.touch.Rating control. There were some internal changes because of Sencha Touch 2.0 design as well as UI changes - added image-less version of the control to showcases.
Also you may find example of action-sheet-like usage of the field in my showcases:
label: 'Star w/ clear',
clearIcon: true //show clear icon right after stars
