It's a bummer that you have to work with the context menu on your first script, because you need to understand that EasyUO is bugged when it comes to using it. EasyUO works great if you are running on RunUO, but there are issues with "exevent popup" on OSI.
I would suggest you look at the EasyUO Wiki information on "exevent popup" to get an understanding of what it does. For your example, you'd want to click the first selection in the menu. However, with the bug for OSI, you actually have to wait for the gump to pop up, and then manually click the correct location. It's pretty dumb.
So I suggest you look at the present documentation, but know it doesn't work as the documentation describes. I would also suggest that you take a look at my code posted here regarding how to manipulate the context menu. You can find that
HEREEdit: In looking at my code, you won't get much from it because it's pretty vague. lol. I use the "exevent popup !findid" without a 4th parameter just to get the gump to pop up. The rest of the code is determining where the gump is at, and then clicking going down the Y-coordinate. Know that there is 18 pixels between each selection. That might help you with the math.
You are in more advanced scripting waters at this point.... Sorry.
