You can even make it easier for yourself when using TTC, so that you *don't*
have to put your data back together again (concatenate).

After you click on <Space> as the delimiter, don't click <Finish>.
Click <Next> to get to the 3rd step of the TTC Wizard.

There, you'll see in the "data preview" window, that the first column
containing Team is selected, by default.
Click on "Do Not Import Column (skip)",
Then, in the "Destination" box, change the column letter to the next column
(depending on where your original data was located), meaning:
If the box displays A1 ... change to B1
If the box displays D12 ... change to E12

THEN click <Finish>

This leaves your original data *untouched*, while copying the numbers to the
adjoining column.
Now, just sort both columns on the number column, and then delete the number
column, leaving your original data sorted, and in it's original form as
data, not concatenate formulas that may have to be transformed back to data
values.
