Wouldn't something like max(min(x, max(y,z)), min(y, z)) work as well,
saving one instruction?

Why not computing the max3(min(x,y),min(x,z),min(y,z))?
For the six possible cases:
x < y < z --> max(x, x, y) -> y ==> works
x < z < y --> max(x, z, z) -> z ==> works
y < x < z --> max(y, x, y) -> x ==> works
y < z < x --> max(y, z, y) -> z ==> works
z < x < y --> max(x, z, z) -> x ==> works
