Well, it is a bit of a red flag if you list them in non-chronological order (unless you wrote a functional resume that was tailored specifically to the requirements for my position, in which case you get bonus points).
You should be able to show career advancement via the achievements you list for each position. There should generally be a trend towards increasing responsibility and successively more impressive feats at each stage. Some lateral movement is fine, but if that's all you've got it suggests that you lack focus/get bored easily.
