I've even noticed a difference between a couple built-in tasks. <property> replaces
${}'s when loaded from a file, but <filter> does NOT. Both DO replace ${}'s when a
single one is defined in the build.xml. With this case it seemed to be that the
<filter> code just chose not to call the <project> function to replace ${}'s with
property values... I don't know why that was, and maybe your case is similar - a
programmer's choice that may have a reason, but it's not readily apparent.

I looked into that a little, but I don't know the code well enough to know.
One thing I did see was that
org.apache.tools.ant.ProjectHelper.NestedElementHandler.init() was handling
'param' differently depending on whether it is the built-in task or the
custom task.
