You can actually replace "*10^" with "*^", which would be the Mathematica's syntax for floating-point exponents. E.g. InputForm[N[5^-9]] will give you 5.12*^-7 as the output.

@Szabolcs thanks for explaining the issue with ToExpression. Your implementation is pretty cool. I did not know about the function StringToStream thanks for introducing...

It works, but let me give one comment: whenever you use ToExpression on data read from a file, you make it possible to inject code into a program even inadvertently (one can never tell what sort of erroneous input the program might get by mistake). I generally try not to use ToExpression for just reading in data (as opposed to converting code)
