Believe me, I've read the man page several times, as well as howtos and 
various other web pages thrown up by google. I've got quoting, escaping 
etc. down pat.

I've tried using a simple variable and an array in test scripts, in a 
teminal, and on the console directly. Always, when the list of options 
are given literally in the oggenc command it works exactly as expected. 
Always, when the option list is in a variable it seems the quotes 
contained in the value of the variable seem to be treated as 'normal' 
characters, rather than acting as quotes. This is independent of 
whether it is a scalar variable or array, and of whether I use single 
or double quotes, and of whether the variable reference itself is 
quoted or not...
