Is there any way to get an orchestral score for some of the epic starcraft 2 music?

this one in particular is one I was looking for. I'm a member of a very large concert orchestra and I'd love to get a concert score of this song and others if possible but I've had no luck finding any at all.

I know some games release the scores and people can purchase them, or sometimes fans have written out scores for songs for other games. So I'm wondering if there is any way at all to get the scores, or if I'm doomed to trying and write it out myself which could take months . . .
