Thx for the clue, I see what you mean.

I had tried to get something similar to your value(item 1 of each +0)
method to work and something wasn't clicking, but after seeing yours, I
think I have it working.

sort lines of tList ascending numeric by (item 1 of each +0) & (item 2 of
each + 0) & (item 3 of each + 0) & (item 4 of each + 0)

The above seems to work fine (and I avoided using value() to avoid an
unnecessary function call), you just have to remember to set the
itemdelimiter to "." otherwise you get the error.  This may be faster
because there aren't a bunch of function calls like my first idea, though
I'm not sure how overhead compares since the numbers must still be
evaluated.

Just did some testing and it seems to be way way faster.  100k lines sort
in 3/4 of a second.
