In a large bowl, stir together flour, brown sugar, baking powder, nutmeg and salt.
Cut in butter until mixture resembles coarse crumbs.
In a separate bowl, toss cranberries with sugar; add to flour mixture along with orange peel and nuts.
Mix lightly.
In another bowl, beat together cream and egg; slowly pour into dry ingredients, mixing with rubber scraper until dough forms. Knead dough 4 or 5 times, being careful not to over handle. Divide dough in half. Turn out onto lightly floured surface. Shape each half into a 6 inch circle.
Cut each circle into 6 wedges.
Place scones on lightly greased baking sheets.
Bake in preheated oven until golden brown, about 20 minutes.
