What type of "dynamic data"? Integers, dates, strings, etc?

You should make the dynamic data returned from a script and add a field
index to the catalog that calls the script. Then you can use the
"sort_on" argument to the catalog to sort on the dynamic data.

This won't work though if the dynamic data changes often for a given
object though...

The above would accomplish this.

You can catalog against Python scripts that are called through
acquisition.
