Any way to include a tab in ooplugin, BracketAfterInList=". "

I have a paper template that requires numbered bibliography like “1.”, “2.” etc, ie a numbered list [1]. But as far as I can tell, I can’t get a nicely lined-up numbered list with Jabref’s settings. Is there any way I can include a [TAB] character in the code for ‘BracketAfterInList’ in my .jstyle file? I didn’t see it in the documentation [2]. That way I could use the paragraph styles to ensure list-like behaviour with numbers and entries both nicely aligned.
