It took me a little while debugging my package before I realised that 
the \mkbibacro macro isn't supposed to be given lowercase text. You 
give it uppercase text (only) and it will either spit out small caps or 
leave things alone.

	    \ifcsundef{\f at encoding/\f at family/\f at series/sc}
	\fontspec{Hoefler Text}
	\mkbibacro{SMALL CAPS?}
	\mkbibacro{SMALL CAPS?}

You could change {#1} to {\MakeUppercase{#1}} in the code above and 
then both \mkbibacro{ANZAC} and \mkbibacro{anzac} would give you the 
same results.
