Preheat oven to 400 degrees. Mix together flour, 1/4 cup sugar, baking powder and salt in a bowl. Cut butter in with pastry blender or fork until mixture resembles coarse crumbs.
Stir in cranberries and orange peel. In a small bowl mix buttermilk and egg. Add to dry ingredients all at once, stirring until mixture is just moistened.
On a floured board, knead gently a few times, but not too much. Form into a patty on an ungreased cookie sheet and cut into 8 wedges with a knife. After cutting into wedges do not move the wedges, leave in the shape of a patty or circle as you originally formed it on cookie sheet.
Bake at 400 degrees for 15 - 25 minutes or until light golden. Mix together powdered sugar and orange juice into a glaze and drizzle over scones.
