I tested that combination in my terminal (which uses DejaVu Sans Mono,
rendered via the bytecode), which was handy.

My version of DejaVu as installed is svn revision 2351 of
2009-03-20T02:27:23.189619Z.

I tried your example of U+61 with U+328 and U+301 in either order.
AKA: » Ä…Ì  « and » ą́ «.

When rendering U+301 before U+328 the two accents are centered on the.
base letter.  However, if U+328 precedes U+301, then U+328 is located
at the right stem; U+301 remains centered.  (The vertical placement is
corrent in both instances.)

Emacs has the same rendering as urxvt.

AIUI, the UCS provides no guidance on this, but Unicode says that U+301
has ccc="230" and U+328 has ccc="202", which means that the cannonical
order is U+61 U+328 U+301.
