I was going to suggest that I think you can pad the single numbers for right alignment but it looks like there are a few wrinkles to that: Number.format(decimalsN[,widthN][,padStr])
@brookteris correct on .nsort for sorting numbers (i.e. Number-type data). The number.format()approach, linked to above results in a _String_. If you were making zero-left-padded number strings, then.sort` would work.
