Preheat oven to 400°. Line a rimmed baking sheet with parchment paper.
In a large bowl, whisk together flour, brown sugar, baking powder, 1 teaspoon cinnamon, nutmeg, salt, baking soda, and cloves. Using a pastry blender or 2 forks, cut butter into flour mixture until it resembles coarse crumbs. (The colder the butter, the better.) Stir in raisins.
In a medium bowl, stir together eggs, sour cream, molasses, and 1 teaspoon vanilla extract. Add to flour mixture, stirring with a fork until a shaggy dough begins to form. Working gently, bring mixture together with hands until a dough forms. (If mixture seems dry and dough won’t come together, add more cream, 1 tablespoon at a time, until it does.)
Turn out dough onto a lightly floured surface, and knead gently until smooth by patting dough and folding it in half 3 to 4 times. Using a rolling pin, roll out dough to a ¾-inch thickness. Shape dough into an 8-inch circle. Using a knife or pizza cutter, cut dough into 8 wedges. Place scones, evenly spaced, on prepared baking sheet.
Brush tops of scones with ¼ cup milk.
Bake until scones are golden brown, approximately 15 minutes. Transfer scones to a wire rack and let cool slightly.
Meanwhile, in a medium bowl, stir together confectioner’s sugar, remaining 1 teaspoon cinnamon, and remaining 1 teaspoon vanilla extract. Whisk in remaining 1 tablespoon milk until glaze reaches desired consistency. Drizzle glaze over scones. Serve warm or at room temperature.
