Because gnuplot has such a wide variety of terminals to use, I guess I 
would prefer to use the gnuplot terminals to match as closely as 
possible the various Octave outputs, and if there is one missing then 
not try to substitute.  Just let the user figure out how to handle the 
output format, e.g., epslatex instead.  Nonetheless, I think 
pdflatexstandalone can be achieved in some way with the cairolatex terminal:

cairolatex

The cairolatex terminal device generates encapsulated PostScript (*.eps) 
or PDF output using the cairo and pango support libraries and uses LaTeX 
for text output using the same routines as the epslatex terminal.

Syntax:

      set terminal cairolatex
                     {eps | pdf}
                     {standalone | input}
                     {blacktext | colortext | colourtext}
                     {header <header> | noheader}
                     {mono|color}
                     {{no}transparent} {{no}crop} {background <rgbcolor>}
                     {font <font>} {fontscale <scale>}
                     {linewidth <lw>} {rounded|butt|square} {dashlength 
<dl>}
                     {size <XX>{unit},<YY>{unit}}

I've never tried it, but I'm guessing that the pdflatexstandalone 
implies the destination is the pdflatex program and not common latex. 
If it doesn't create exactly what is needed, then I can go to the 
gnuplot discussion list and see if it makes sense to add a pdflatex 
terminal.
