Kevin,
don't nest the expression tag ${} ie use:${string::contains(db.type,'oracle')}
instead of:
${string::contains('${db.type}','oracle')}
${} now denotes an expression rather than just a property and to use a property inside an expression just use its name. If the expression consists of nothing but a property name then the value of that property will be returned. So : ${somefunc(foo)} says perform some function on property named foo returning the result and: ${foo} says return the value of foo
I hope that makes it a little clearer. Proably somthing to put in the FAQ

Can any of you elite NAnt expression creators out there help me out?
I am trying to do a simple string compare against a property that is set by a parent target. If you have any suggestions as to the proper NAnt way to accomplish such things I am all ears. I am on the nightly as of 5/20/2004 of both NAnt and Contrib.
<if test="${string::contains('${db.type}','oracle')}"> <property name="connection.string" value="Provider=msdaora;Data Source=${db.servername}; User Id=${db.saname};Password=${db.sapass};" /> </if>
<if test="${ '${db.type}' = 'mssql'}"> <property name="connection.string" value="Provider=sqloledb;Data Source=${db.servername}; Initial Catalog=${db.name}; uid=${db.saname};pwd=${db.sapass};" /> </if>
