You are running into the Geocoder error OVER_QUERY_LIMIT (from experience you can geocode approximately 11 addresses quickly before running into the rate limit). To verify add an else to the status check:

        geocoder.geocode({'address':address}, function (results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                coords.push(results[0].geometry.location);
            } else alert("Geocode failed, status = "+status);

• see this question on SO for a way to throttle the geocode requests
