I'm afraid I can't really understand your requirements, but
it is very common for unterminated numbers to cause problems.
In the above two lines, \fi is processed before tex knows that
the "1" is all there is to this number. Try putting
  a space or \relax after the "1". For example:
     \expandafter \iffalse \topmarks1 \fi
or
     \expandafter \iffalse \topmarks1\relax\fi
The space is absorbed by tex in the process of parsing the number.
\relax may or may not be harmless, but it certainly won't contribute
any visible tokens.
