Since your StyleSheet is a Folder, you should be able to use 'objectIds' 
and company with a meta-type argument.  I'm not sure what your 
parenthesized bit means.

The 'title' should be accessible as a simple attribute.  I presume that 
'styletype' is defined on a ZClass propertsheet, so you may need to 
write something like "ss.propertysheets.get('mysheet').styletype"

Hmm.  Here an utterly untested code snippet that may help, intended to 
be the body of a Script in StyleBook

##parameters=a_title, a_type

props = []
for ss in container.objectValues(['StyleSheet']):
     if (ss.title == a_title and
         ss.propertysheets['mysheet'].styletype == a_type):
         for p in ss.propertysheets.get('mysheet').propertyItems():
             props.append('%s: %s' % p)
         return '; '.join(props)
