Every folder/context has a sort property field that is set by default to 0. Informant's Project and Context views sort by the sort property and then by title. Since all projects/contexts have a sort property default of 0 the views are de-facto sorted by title - alphabetically.

Projects can be sorted in the Informant task view by going into the projects view and dragging the projects into the order that you are seeking.  This order is not a syncable item and will need to be done manually on all devices.
