If you are willing to use tmp files you can:
cut -d, -f1 <input >tmp1
cut -d, -f2 <input >tmp2
cut -d, -f3 <input >tmp3

paste -d, tmp1 tmp3 tmp2 >file_I_wanted
rm tmp1 tmp2 tmp3

There's probably a clever way to do this with tee and fifos to handle
unlimited stream sizes but I'm too lazy to work it out.
