But once you run into 6000 and above you start running into ports that are dedicated and well-known for offering other services like remote-X and dozens of other things. Just because you find an active port on a remote machine, doesn't mean it will accept a telnet connection and talk to you using the telnet protocol. It could be any of a thousand other services that also use ports above 1023... IE 5002 is "radio free ethernet" 5308 is "cfengine" 5999 is "cvsup file transfer" 6000 is "X11" 7000-7009 are all registered already. 11720 is h.323 conferencing stuff. Etc...
