As Aia noted, the version of the Korn shell you're using makes a big difference here. With a 1993 or later version of ksh, your code might work. I'm not sure in this case that the OS matters much, but when asking questions like this, it is always a good policy to tell us what environment you're using.
The fact that the error messages that ksh printed did not come from the script you showed us makes us wonder what the other two lines before the if statement looked like and what the line that you removed before the elif looked like???
And, the fact that you're using sed to remove commas from the uptime output makes us wonder what locale you're using. The text in your output is English, but if you're removing commas, is the locale European or are the actions on the commas just there to confuse us???
The OS would be significant, since the output of uptime is not the same.
Also, if it is a Linux kernel /proc/loadavg could be used instead of uptime.
Instead of dealing with another external program and the output would not have comas:
