In shallow dish, combine all ingredients except meat and olives. Score steaks by making shallow cuts in crisscross pattern on one side; add to marinade. Marinate at room temperature for at least 2 hours, turning several times.
Remove steaks, reserving marinade. Place on grill about 3 inches above red hot coals or at high setting of electric or gas barbecue. Baste meat several times with marinade; cook for about 4 minutes per side for rare; 6 minutes for medium. Garnish with olives on a wooden pick.
