If Richard's double set of "()"'s holds up, then I re-submit my code:

Game24 KiXtart Golf running under KiXtart v4.11

Numbers = 1, 2, 3, 4
Please doublecheck your solution to guarantee a correct result
1.0*(2.0*(3.0*4.0)) = 24

Numbers = 2, 2, 6, 8
Please doublecheck your solution to guarantee a correct result
2.0+(6.0+(8.0*2.0)) = 24

Numbers = 4, 4, 6, 6
Correct answer answer, there is no solution to this combination

Numbers = 3, 3, 8, 8
Please doublecheck your solution to guarantee a correct result
8.0/(3.0-(8.0/3.0)) = 24

Numbers = 0, 4, 6, 8
Please doublecheck your solution to guarantee a correct result
0.0+(6.0*(8.0-4.0)) = 24

Numbers = 3, 4, 7, 7
Please doublecheck your solution to guarantee a correct result
3.0+(7.0*(7.0-4.0)) = 24

Numbers = 1, 2, 8, 9
Please doublecheck your solution to guarantee a correct result
8.0*(9.0/(2.0+1.0)) = 24

Time: 421 ticks

{edit}
Thanks Erik, Removed "exit" reduced score by four.
KixGolf v3.0.3 score = 314, running under KiXtart v4.10

code:
function game24($a,$b,$c,$d)

   Dim $h, $p, $q, $r, $s, $t, $v, $, $x, $y

  $h = "+","-","/","*"
   for $y=1 to 4
      for $x=1 to 4
         for each $p in $h
            for each $q in $h
               for each $r in $h
                  $ = ".0"
                  $s = ""+$a+$+$p+"("+$b+$+$q+"("+$c+$+$r+$d+$+"))"
                  $t = execute("$$v=$s")
                  if abs($v-24)< 1E-9
                     goto E
                  endif
               next
            next
         next
         $ = $b
         $b = $c
         $c = $d
         $d = $
      next
      $ = $a
      $a = $b
      $b = $
   next
   $s = ""

   :E
      $game24 = $s
endfunction
