I found the command name which will let you run it from a script.
You can run any command in Inventor using the code below if you have the name of the command.
Function Run_CMD(ByVal cmd As String) As Boolean
ThisApplication.CommandManager.ControlDefinitions.item(cmd).Execute
End Function
'Running the Assembly Productivity Alpha Sort Component command
run_cmd("AssemblyBonusTools_AlphaSortComponentsCmd")
Full list of productivity commands and their command name.

You can also use this bit of code from the api help to list all commands.
Sub PrintCommandNames()
Dim oControlDefs As ControlDefinitions
Set oControlDefs = ThisApplication.CommandManager.ControlDefinitions
