Preheat the oven to 350°F. In a small bowl, using your hands, massage the orange zest into the sugar.
Add the flour, salt, and baking powder to a large mixing bowl. Whisk until all clumps are broken up and it's well incorporated. Then, add the butter, eggs, orange zest sugar, orange juice, and vanilla extract to the bowl and whisk until well incorporated.
Add the fresh cranberries to the bowl and use your hands to incorporate them into the dough.
Press the dough into a 1-inch-thick disc, and use a sharp knife to cut it into 6 triangular pieces.
Spread the scones out on a parchment paper-lined baking sheet and brush them with melted butter. Then, bake them at 350°F for 30 minutes.
While the scones are baking, make the glaze by whisking together the powered sugar and orange juice in a small bowl until smooth.
Drizzle the glaze over the scones, then serve and enjoy!
