But this is a CFMX-only solution. (Which is what he did specify, although he later was suprised it didn't work on 5.0)
He also seemed confused by the [:space:] class, which included more than just the chr(32) character.
If he wanted to correctly capture the words with the non-space word seperators, I would have used a regex instead of the listgetat function.
But I was reading into his purpose. It seems like he wants to compare the string with another version of the string. In that case, I thought simplifying the potential non-words would actually help, rather than hurt. Replacing all tabs, line feeds, etc with spaces would (in html) look the same, but the comparison would be more likely to match.
Egads, that's too much info.

This does approximately the same as the regexp, but not quite. This will
only work if the space is there as a delimiter (and not a tab or a comma
without a space). If you add delimiters to the listGetAt, you don't put
the sentence correctly together. However, it will work in most cases.
Both our solutions have a problem if the sentence has two words and you
ask for three. In the list solution, just make sure that the
numberOfWords is less then ListLen(sentence," "). For the regexp try
Regexp = "(\w+\W+){0," & (i-1) & "}" & Regexp
