Try this code (replace ‘Group’ with your bone group name):
C.object.pose.bone_groups.active_index = C.object.pose.bone_groups.find('Group'); O.pose.group_select()
If you want to deselect all other bones use this:
O.pose.select_all(action='DESELECT'); C.object.pose.bone_groups.active_index = C.object.pose.bone_groups.find('Group'); O.pose.group_select()
