What do you mean a good script?
If you mean scripts you need to get from town to monsters you can make them yourself pretty easily. Like I said before 10x

.
Go to the bots loop tab
Go to town and walk to the point you'd like to start
Record script (check auto add all movements)
Start walking to you desired trainings spot
Save the script
Load the script
DONEEE!
Now, you might wanna restart you bot before you can load the script. But after that it should work.
If you wanna make a script manualy I highly recommend this site (just select Sbot, yea it's not iBot but it works).
