WJFFM:
$ mkdir abc && cd abc && touch 35ms 40ms 80ms
$ ls
35ms  40ms  80ms
$ ls `ls`
35ms  40ms  80ms

In trying to think of things that might be interfering, do you have a 
problematic alias or shell function named ls?  For example, if ls is 
aliased to 'ls --color=always', and those particular files would be 
colored by your dircolors settings, then I could see that causing a 
failure (hint, use --color=auto, not --color=always, when aliasing ls). 
  Also, running under 'set -vx' may be informative.
