Subject: Sorting numbers.

I read a line from a CSV file as the following:
    fooone,22,114,66,125,footwo
and I would like to sort the numbers from index
1 to 4, but I can't convince the sort function
to work with integers instead of strings. The result
of sort is always 114,125,22,66 as it is sorted by
the first ASCII character.
The to_i function doesn't seem to be appropiate.
Can the sort work with int's or is only designed
to work with strings ?
I'm using Ruby 1.9.1 p378 with the 'new' built-in CSV.

Any clue welcomed, Andreu.
