Simple scoring question

[matthask]

I'm new to scoring - simple question: Nobody is on base, and a batter hits a hard line drive down the third base line in fair territory; batter rounds first, rounds second, but gets tagged out at third by a great throw from the left fielder to third base. How is it scored?

In play, Out, line drive, mark position, 7-5, done? This results in "line drive to left fielder for an out", which isn't what happened.

In play, double, hard line drive. What happened to runner? Out at third, tagged out, 7 to 5.
