The use of column vectors and right-to-left ordering is the standard in most mathematical texts, and id the same as used in OpenGL. It is, however, the opposite of Direct3D, which has inexplicably chosen to differ from the accepted standard and uses row vectors and left-to-right matrix multiplication.
OGRE deals with the differences between D3D and OpenGL etc. internally when operating through different render systems. OGRE users only need to conform to standard maths conventions, i.e. right-to-left matrix multiplication, (OGRE transposes matrices it passes to D3D to compensate).
The generic form M * V which shows the layout of the matrix entries is shown below:
[ m[0][0] m[0][1] m[0][2] m[0][3] ] {x} | m[1][0] m[1][1] m[1][2] m[1][3] | * {y} | m[2][0] m[2][1] m[2][2] m[2][3] | {z} [ m[3][0] m[3][1] m[3][2] m[3][3] ] {1}
