Heat oven to 425°F. Lightly grease cookie sheets. In large bowl, combine flour, 3 tablespoons of the sugar, baking soda, cream of tartar, salt and orange peel; mix well. With pastry blender or fork, cut in margarine until mixture resembles coarse crumbs. Stir in dried fruit bits. Add milk; stir just until dry ingredients are moistened.
On lightly floured surface, gently knead dough 10 times. Roll or pat dough to 3/4-inch thickness. Cut out scones with floured 3-inch round cutter; place 2 inches apart on greased cookie sheets. Sprinkle remaining 1 tablespoon sugar evenly over scones.
Bake at 425°F. for 7 to 12 minutes or until light golden brown. Serve warm.
