To expand on that:

*) Wait until everyone arrives at the next tee pad.
*) Call out the hole number that was just played.
*) Call out the first player's name. If it is yourself, call out your own name.
*) They report the total number (throws and penalties) they had on the hole. If it is yourself, say your score out loud.
*) Write that number down, and read it back to group. Even if it is yourself, read that score back out loud just like any other.
*) Repeat for each player in the group.
*) Call out the new driving order.

Do it the same every time. Be consistent with use of nicknames. For players with the same name, find a clear method to distinguish them, and stick to it. Speak so that everyone in the group can clearly hear you. There is no need to editorialize about the scores as you take them. Coach everyone to report their score by number (2, 3, 4, etc.) not any other method (par, deuce, bogey, etc.).
