Main_OnCommandEx()

void Main_OnCommandEx(int command, int flag, void* proj)

You can call any REAPER action from ReaScript by using this API function.

e.g. RPR_Main_OnCommand(actionnumber, 0)

Find the action number for a given action by opening the Actions list, scroll the window right to show the action numbers. For example, from ReaScript you can call the REAPER action "Item: Split item under mouse cursor", like this:

RPR_Main_OnCommand(40746, 0)

This and the RPR_MIDIEditor functions are the APIs you need to start with if you're going to use ReaScript as an advanced macro language.
