This is the way I do it:
r.out.ascii map=yourmap>yourmap.ascii

yourmap.ascii will have grass header information that needs to be changed to the header arc/info requires. So type "help asciigrid" in Arc and it will tell you the header format that arc/info needs. You need to change the grass header to the arcinfo header by editing yourmap.ascii. Then use, asciigrid in arc.
