You like semicolons too well. This works:

SRSort = Compile[
     {{f, _Real, 1}}, Module[{lambda, i},
      lambda = Length[f]; Index = Table[0,
         {lambda}]; For[i = 1, i <= lambda, i++,
        Index[[i]] = f[[i]]; ];
       Index]];
data = RandomArray[BinomialDistribution[12, 0.3], 12]
copy=SRSort[data]
{5, 3, 2, 3, 4, 3, 6, 6, 2, 6, 2, 3}
{5, 3, 2, 3, 4, 3, 6, 6, 2, 6, 2, 3}

But this works a lot better:

copy=data
