There are no scripts involved in this. As much as it may disturb basement-dwellers, exercising your Swedish freedom of information involves showing up at the specific public office/gov't branch/etc yourself.
You have to show up at the court in person and ask to see any documents pertaining to specific IP-addresses. The court is not obliged to prepare lists or in any other way format the data; they will just hand out the entire court document itself for you to sift through. The work is also expected to be "reasonable", which is why you just can't show up with 1000 ip-addresses every day.
The general idea behind the Swedish freedom of information is that you know what you're looking for, not that you're scanning everything in order to find something interesting. This of course makes it hard to apply in cases like IPRED where you may not be informed that you are under investigation until after a whole month.
