Preheat oven to 400F/200C. Soak cherries in orange juice for 30 minutes.
Meanwhile, in a large bowl combine flour, sugar, baking powder and baking soda. Cut butter into the flour mixture with a pastry blender or pulse it in a food processor until the mixture resembles bread crumbs.
Beat the eggs and milk with a fork and drain cherries. Make a well in the flour mixture and pour in the milk and eggs, add cherries and chocolate, mix well until you form soft dough. (If your dough is too sticky add a bit of flour).
Turn out on a floured surface and roll it out ¾" thick. Cut scones with a round pastry cutter. You will have 16-18 scones.
Place on a parchment lined baking sheet, and brush the tops of your scones with half & half or single cream. Sprinkle with a bit of sugar if desired. Bake in the oven for 15 minutes.
