To clear up some misconceptions here, math does indeed work in a
constraint expression, but "is undefined" appears to be how condor_q
-better-analyze prints the expression '(Value =?= UNDEFINED)' and is
not a valid construct.  The expression you want is:

condor_status -const '( Arch == "X86_64" ) && ( OpSys == "LINUX" ) && ( ( CkptArch == "X86_64" ) || ( CkptArch =?= UNDEFINED ) ) && ( ( CkptOpSys == "LINUX" ) || ( CkptOpSys =?= UNDEFINED ) ) && ( Disk >= 10000 ) && ( ( Memory * 1024 ) >= 10000 )'

Note that "CkptArch" and "CkptOpSys" both come from the JobAd, so the
tests for "UNDEFINED" are needed to get any output from condor_status.

An equivalent expression would be:

condor_status -const '( Arch == "X86_64" ) && ( OpSys == "LINUX" ) && ( Disk >= 10000 ) && ( ( Memory * 1024 ) >= 10000 )'

Which is almost what you used here:

That is a possibility.  What version of Condor are you running?  I
believe you need at least 6.8.2 to support checkpointing on X86_64.

I would certainly start with getting a simple shell script to run as a
Vanilla job before trying anything more complex.
