Your script (entry point script and supporting library scripts) must use either SuiteScript 1.0 or SuiteScript 2.0. You cannot use APIs from both versions in one script.

You can, however, have multiple scripts that use different SuiteScript versions. These can be deployed in the same account, in the same SuiteApp, and on the same record.

The map/reduce script type is a new functionality introduced with SuiteScript 2.0. You cannot use nlapiScheduleScript(scriptId, deployId, params) to schedule a Map/Reduce script. See Map/Reduce Script Type for more information.
