I assume you mean (the above is how rpm -qi shows it though):

Prefixes: /opt /etc

The prefixes are passed to scriptlets via $RPM_INSTALL_PREFIX<n> 
environment variables, <n> is the index of supported prefixes starting 
from zero. So in the above,

/opt is $RPM_INSTALL_PREFIX0
/etc is $RPM_INSTALL_PREFIX1

So the scriptlet example becomes:

     echo `hostname --fqdn` > $RPM_INSTALL_PREFIX1/myapp/host.conf
