I'm guessing you have Shift+# already mapped to something (they default map to your first 6 pages of action bars). If you remove the mapping you should be able to use the shift key modifier.
That was it
boy do i feel silly.

Edit:
I believe it is:

/use [flyable] FlyingMountName; LandMountName
this is a much better job altogether.

thanks guys
