rhinoscript can:

[StartupScriptCount](https://developer.rhino3d.com/api/rhinoscript/application_methods/startupscriptcount.htm)  
Returns the number of startup scripts.

[StartupScriptList](https://developer.rhino3d.com/api/rhinoscript/application_methods/startupscriptlist.htm)  
Return the list of startup script files.

[AddStartupScript](https://developer.rhino3d.com/api/rhinoscript/application_methods/addstartupscript.htm)  
Adds a startup script to RhinoScript.

[DeleteStartupScript](https://developer.rhino3d.com/api/rhinoscript/application_methods/deletestartupscript.htm)  
Removes a startup script to RhinoScript.

my guess is, if you add a file with .py this will also run.

You might also workarround by calling a command of a custom (your) (rhinocommon) plug-in.

rhinoscript is directly accessing the c++ sdk methods.  
phyton and rhinoscriptsyntax are based on rhinocommon.

there might be difference of what is accessible.

i never tried, but you might also be able to add a startup script using a macro.  
starting with  
!-\_documentproperties \_options

because of this [thread](https://discourse.mcneel.com/t/addalias-lastloadedscript-and-addstartupscript-in-python-creating-commands/47360/4) i think @stevebaer might be the right person to answer your question with more details / options / alternatives.
