Not that this is a solution, but in pharo, you get the same answer as
GemStone (i.e., the exponent is ignored).... #asNumber is based on a port
of SqNumberParser, so that "makes sense."

This form of the printString produces the expected answer:

  '7.3470570000000004e02' asNumber.

Note the lower case $e and absence of $+ ...

With that said, I know that GemStone prints it's floats with a plus sign in
the exponent and this is a bug that has been fixed in 3.2 ...

SqNumberParser>>exponentLetters controls the list of exponents expected and
could be modified to include capital letters ...

The class ExtendedNumberParser will parse numbers with $+ in the exponent
so overriding SqNumberParser class>>on: to directly use
ExtendedNumberParser ... allows asNumber to accept $+ ,,,

so a patch to SqNumberParser>>exponentLetters and the SqNumber class-side
methods would probably get you past this hump...
