Are you questioning the inclusion of "e" (scientific notation) or are the coordinates incorrect?
Try this script which avoids the use of $ (not recommended for maxscripts) and creates a comma delimited file which can be read by Excel.
outputFile = createFile "output.txt"
obj=selection as array
for o in obj do format "\n%,%,%,%" o.name o.pos.x o.pos.y o.pos.z to:outputfile
close outputFile
