Applescript to search open Safari Tabs

I found this great Applescript that will search through Safari's open tabs and activate it. I found that if I save it as an Applescript app, it works great with LaunchBar.

However, I'd like to input the search term directly into to LaunchBar by using the "on handle_string(theString)" somewhere in the script. Is this possible to do with this script?

Here's the script:

set question to display dialog ("Find Safari tab:") default answer ""
set searchpat to text returned of question

tell application "Safari"
   set winlist to every window
   set winmatchlist to {}
   set tabmatchlist to {}
   set tabnamematchlist to {}
   repeat with win in winlist
      set ok to true
      try
         set tablist to every tab of win
      on error errmsg
         --display dialog name of win as string
         set ok to false
      end try
      if ok then
         repeat with t in tablist
            if searchpat is in (name of t as string) then
               set end of winmatchlist to win
               set end of tabmatchlist to t
               set end of tabnamematchlist to (id of win as string) & "." & (index of t as string) & ".  " & (name of t as string)
               --display dialog name of t as string
            else if searchpat is in (URL of t as string) then
               set end of winmatchlist to win
               set end of tabmatchlist to t
               set end of tabnamematchlist to (id of win as string) & "." & (index of t as string) & ".  " & (name of t as string)
               --display dialog name of t as string
            end if
         end repeat
      end if
   end repeat
   if (count of tabmatchlist) = 1 then
      --display dialog "one!"
      set w to item 1 of winmatchlist
      set t to item 1 of tabmatchlist
      set current tab of w to t
      set index of w to 1
   else if (count of tabmatchlist) = 0 then
      display dialog "No matches"
   else
      set whichtab to choose from list of tabnamematchlist with prompt "The following tabs match, please select one:"
      set AppleScript's text item delimiters to "."
      if whichtab is not equal to false then
         set tmp to text items of (whichtab as string)
         set w to (item 1 of tmp) as integer
         set t to (item 2 of tmp) as integer
         set current tab of window id w to tab t of window id w
         set index of window id w to 1
      end if
   end if
end tell

Thank you!
