Any larger than 3000pts you have to convert to curves and scale from there.
There used to be a 3,000 pt limit, but it was removed some versions ago.Maybe it is still there in the Mac version, I don't know, but it is possible to go way higher in the Windows version.The limit now seems to be around 608,000 pt, but then you will no longer be able to see the text because it doesn't fit inside the maximum drawing area.
