The steps are:

get a reference to your tasksequence,
add a task by method addtask (it will be added as last task),
set a rank for last new added task in the sequence by property rank.

Limits:

tasksequence task rank is not already in execution.
best - tasksequence is not in execution at all.
There is not any coding or conditions which depends on strict ranks of a default transport tasksequence.

Properties in manual about task types.

uitilize keys for item and station are identifiers to free or interrupt a taskexecuter from an utilize task. Otherwise you free possibly more taskexecuters than you want.

on receive tasksequence is event where can get access to a tasksequence reference. It is a trigger in dispatchers and taskexecuters. This means you can edit a trigger source code or you evaluate the event in event driven activities in process flow.

Besides this you can evaluate tasksequences in a treenode of taskexecuters and dispatchers. It is called tasksequencequeue.

Or you can get access of an currently executing tasksequence from

activeTasksequence.

Wait for task and utilize task are suspending tasks in a tasksequence. A taskexecuter (operator, vehicle) are locked in a state and won’t get available.

I call such tasks “ get them something to do”. For statistical purpose you set a useful state.

a utilize task ends by command freeoperators. A wait for task ends by any new added task to currently active tasksequence. If this added task shouldn’t have any effect a Tasktype of “tag” does this. Probably this mechanism watches the property of number of total tasks.
You find utilize tasks by default in activities calling operators for setup and processing in processor class objects.
