Hi Joshua,

if you prefer using the comma seperated lists and there's no DBAL compliant 
way of filtering via the database (thx for your hint Alex, you're right :), 
IMHO you have to get the whole comma seperated list string and 
filter/process it via your PHP code. As Alex pointed out there are helper 
functions in t3lib_div - did you try t3lib_div::inList()?
