This request is implemented in the attached external script, (at)taskchain@.
Make the script executable with:

chmod +x taskchain

You can then do:

./taskchain 100 101 102 103 104

If this request were implemented internally, would filters be allowed? How would

task  chain

be treated? I guess it could order the tasks by ID or creation date.

Note that in addition to the thread referenced in the original post, there was another thread with a similar feature request:
http://taskwarrior.org/boards/6/topics/1569
An extrenal script could implement that request as well but would also need a way of getting the task number of the commands created. You would only need to get the task ID of the first add.
This could be a job for sed. The following will return the task ID of the add:

task add first_description | sed -r 's/[^0-9]*([0-9]+)\./\1/'
