problem with a variable in pdfinfo, probably something obvious

[David Carlisle]

It's a bit hard to follow your example fragments but most likely you need
something that expands to the value and latex \input is not expandable
You can probably use

\makeatletter
\mjmaddbib{pages}{ \@@input \mjmbasename.last_page }
\makeatother

to use the expandable primitive input  (note no {}) but depending on ...
things you may get an unwanted \par from the end of the file.
