Since I use Xcode 5 and the new iOS 7 simulator to run UIAutomation tests with Instruments, dragInsideWithOptions and dragFromToForDuration functio
This is a bit old but it seems that dragInsideWithOptions is still not working.
For a UIScrollView these methods can be used:
scrollUp
scrollDown
scrollLeft
scrollRight

Ex:
UIATarget.localTarget().frontMostApp().mainWindow().scrollViews()[0].scrollRight();
Hope it helps!
