scratch dimensions are used all over the place, so it's dangerous to use
them to pass values in this way, instead use:
\expanded{\externalfigure[pdftex-z][type=pdf,width=\the\dimen0,height=\the\dimen2]}
is one way,
\edef\MyWidth {\the\dimen0}%
\edef\MyHeight{\the\dimen2}%
\externalfigure[pdftex-z][type=pdf,width=\MyWidth,height=\MyHeight]
is another one. So, either expand, or use intermediate macros.
(no reason to set the type=pdf here)
