QXP: Specifying the first space AFTER

Hello,
Want to see if I can automatically “rundown” my text in price book:

So I need this:

2,500,000 Modesto, CA Special Bond, Community Facilities District No. 4

to be this:
2,500,000 Modesto, CA Special Bond,
Community Facilities District
No. 4

So I want to specify the first space AFTER
the second tab character
but also AFTER 25 generic characters

and replace it with a soft return.

I know my replace code will be


	tell document 1 of application "QuarkXPress"
		tell current box
			tell story 1
                                 set first text where it is (ascii character 32) to (ascii character 7) 
                        end
                end
        end

but first I need to specify the particular space character I want to target.

Can I get a hand with that?
