I used the research done by Argentinian sports magazine el graffico as a source rather than rsssf, they have included Pele at 757 at place 3 with the criteria being that they counted offical goals and did not count goals scored in club friendlies, club organized tournaments, summer/winter tournaments, preseason tournaments,matches that did not involve the professional side, and festive matches.
Im not sure its 100% accurate of course as is with most of these statistics from the past but ist pretty cool cause the orginal file contains up to the best 160 goalscorers, Messi wasn't included cause they published that edition in March 2012, also the active players on the list may have lower numbers than they currently have.
I uploaded the pdf file.
