`man top` says:

        ...The default key for sorting is pid,  but  other  keys
        can be used instead.  Various output options are available.

OPTIONS
        Command  line  option  specifications are processed from left to 
right.
        Options can be specified more than once.  If  conflicting  
options  are
        specified,  later  specifications override earlier ones.  This 
makes it
        viable to create a shell alias for top with preferred  defaults  
speci-
        fied,  then override those preferred defaults as desired on the 
command
        line.
...
        -u     Deprecated, equivalent to -ocpu -Otime.



Therefore:
   alias top='top -ocpu -Otime'
   alias topold='top -opid'

Perhaps `topold` will alias to `top -ocpu -Otime -opid`, but this 
doesn't matter, as the -opid will over-ride the -ocpu.

HTH,
