positioning multiple charges on an ordinary

It seems to be impossible to position two different charges on an ordinary.

The closest I can get is using `between`, but that means one of them is duplicated:

`argent on a chief azure a harp between two stags heads or`

This positions the three charges on the ordinary as you'd expect.

If you change `between` to `beside`, though:

`argent on a chief azure a harp beside a stags head or`

The harp gets positioned on the chief, but the stags head does not.

Also, the `between` only works if written `on a between `. If you write ` between on ` it does not work, even though the simple ` on ` in that same order works fine. Basically the positioning of charges on ordinaries is super inconsistent in what works and what doesn't.
