Preheat oven to 375 degrees; grease cookie sheets. In a large bowl, combine the flour, sugar, baking powder, salt and baking soda; blend well. Using a pastry blender or fork, cut in the margarine until the mixture resembles coarse crumbs. Add the orange juice, milk and orange peel; stir just until the dry ingredients are moistened. Stir in the chocolate chips. Drop by heaping teaspoonfuls two inches apart onto the cookie sheets. In a small bowl, combine the sugar and cinnamon; sprinkle over the scones. Bake for 8 to 10 minutes, or until light golden brown. Immediately remove from the cookie sheets. Serve warm.
