While easyUO works ok, openEUO works great: you can do so much more with
an actual programming language, Lua. And it's orders of magnitude faster.
Here's some helpful links:
Lua 5.1 Reference Manual - http://www.lua.org/manual/5.1/index.html#contents
openEUO wiki - http://www.easyuo.com/openeuo/wiki/index.php/Main_Page
Also, I've found it easier to write the scripts in a text editor (syntax highlighting, line numbering, auto-brackets etc)
and for testing the script to use dofile("script_file_name")
EDIT:
Proof of speed difference -- for loop, adding 1 to a variable one million times:
j = 0
for i = 1,1000000
j = j + 1
openEUO: about 0.1 seconds
easyUO: about 250 seconds (4+ minutes)
