No. Script tasks can't execute smart services, for one thing - and also it wouldn't really work in an a!forEach loop. Any reason you can't accomplish what you're after using a standard Create Folder node with MNI?
well i have a to create folders for new items that get created daily. I don't know how many will be created daily, but I know that in the past it was more than 1000 items, wich causes issues with MNI.
