Why surprised? 
I don't know of any software that DOES support 960. There are no databases for 960 either.
Doesn't even support chess960? Really?
Sort:
SCID doesn't support chess960. And I don't think it will support 960 in the future - http://sourceforge.net/p/scid/mailman/message/25993088/
There used to be a fork of scid (scid960) which supported 960 but now I can't find it anywhere. I've heard that another fork of SCID ChessDB can handle 960 but I'm not sure..
One think you can do is you can use winboard and download stockfish or critter or hamster to play 960. Winboard does support 960 and it's called FRC there..
There is a 960 patch in the ScidvsPC source directory (patches). It was kindof working, but the original authors have abandoned it (at least for the moment), and debugging/testing it isn't a priority for me.

Arena chess supports chess 960
Surprised because, compared to everything else the program does, it seems so easy.
Scid's strength is speed from Shane's tight design.
Unfortunately it means it's (maybe) impossible/not-worth-the-effort to add fully working 960 support.

It is certainly not impossible (what is referred to above is very close already). Whether it is worth the benefit to those who are interested in 960 for Shane (or someone else) to write the necessary code is unquantifiable.

There is little point in opening databases for 960, since 1000 times as much material would be necessary to get a comparable coverage, and the material available is, and probably will continue to be, much, much more limited.
Scid vs PC 4.17 now includes a working and mostly tested "patch" for Chess 960 
But i don't have the time to support this, so have not made any windows binaries. The patch is in the "patches" directory of the source code.
Also, we have recently updated the windows visual studio makefile, so it is easier to compile. New Makefile.vc is in subversion only. Sorry i don't have more time. S.A
I tried to load a chess960 game in 4.11 and it died when it got to the O-O-O.
Also when making moves in the GUI I can figure out no way to castle...
