There are by my count 10 or so 1998 and 1999 SE Sports in my hometown, and mine is the ONLY one that has a V6. (I know this because all the others don't have the V6 on the tach, or the 24v emblem on the trunk.) In fact, I think I have one of three out of 20 or so tours in town with a V6. People around here don't order cars, they just buy whats on the lot, and our local Ford dealer ordered every Contour he sold as a 4 cylinder. So yeah, you can find a SE Sport made in 98-99 with a zetec.
