The "cost" (of the least-cost path) is calculated based on an impedance attribute which you define in a network dataset. Impedance can be time or distance, or even a more abstract variable such as "scenic value".
Note: RouteTask, and other routing related classes, were added in version 1.2 and requires ArcGIS Server 9.3.1 or above and a "route" layer. A "route" layer is a layer of type "esriNAServerRouteLayer", for example, http://tasks.arcgisonline.com/ArcGIS/rest/services/NetworkAnalysis/ESRI_Route_EU/NAServer/Route.
