If you can't get the locking nut to thread on to it, I'd give the following a try. I'm a bit of a ghetto bike diy-er so apologies if I get names of bits wrong:
Firstly take the top locknut thing off (the bit thats on the piss), then slowly unscrew the top bearing race (the bit with the knurled edges). You want to turn it clockwise and anticlockwise slowly over the area at the very end of the steerer tube, hopefully this will realign the shitty bits of thread at the very end. Do it slowly, and try not to take it completely off until all the threads all the way up are nice and free-running with no resistance.
This is what I do when cutting a section off a piece of threaded rod for stuff. stick a few nuts on it before you cut it, then slowly screw them off, re-aligning the threads on the cut end.
[edit] oh and that nut locks the top race of the headset down to a set position (like winding two nuts tight against each other to lock them on a thread). Essential, since you don't want your top race really really tight so it rapes your ball bearings, and it'll unscrew itself if it's any looser without the locking nut.
