In a medium saucepan, combine blackberries, honey, vinegar, wine, and a pinch of salt. Mash berries lightly with a fork. Bring to a boil, reduce heat, and simmer, uncovered, about 8 minutes, until sauce is slightly thickened.
While sauce cooks, in a small bowl combine ½ teaspoon salt, cinnamon, cumin, cayenne, and black pepper. Gently rub both sides of tilapia fillets with spice mixture.
In a large skillet, heat olive oil over medium-high. Sauté fish 2-3 minutes, until golden, then turn and sauté 2-4 minutes longer, until cooked through. Transfer to serving plates and top with blackberry sauce. Serve immediately.
