You could do something like this as bundle command:

#!/bin/sh
chars=`perl -ne '$m = length if length > $m; END{print $m}'`
cat <<__EOF__ | osascript
set fontscale to 6.25
set gutter to 54
set scrollbar to 16
set maxwidth to 1920
tell application "TextMate"
	set d to bounds of window 1
	set l to item 1 of d
	set t to item 2 of d
	set r to l + (fontscale * $chars) + gutter + scrollbar
	if r > maxwidth then set r to maxwidth
	set b to item 4 of d
	set bounds of window 1 to {l, t, r, b}
end tell
__EOF__

It's not perfect but gets pretty close in the testing I just did.  
You'll have to figure out your own fontscale. To get close download  
FreeRuler [1]. Set your wrap column to 100 and make your right margin  
indicator visible in the TextMate prefs then just measure with  
FreeRuler and divide the pixel count by 100. Obviously adjust gutter  
and maxwidth as appropriate.

Well I primarily use TextMate for Python and prefer lines no wider  
than 78 chars. In fact, people who code lines wider than that should  
be shot -- at least until TextMate's wrapping is improved. :-)

That reminds me of another nit ... when scrolling horizontally I'd  
much prefer if the gutter did not scroll out of the window frame.
