Your problem isn't the lack of "$" (glob patterns always anchor to the
start and end so ^ and $ operators are unneeded), it's your use of "*". 
"*" in a glob pattern means "match any character", and is equivalent to
the regex ".*" .

Try "/var/tmp/exec.<->".  <-> is the <x-y> numeric range operator with
no minimum or maximum number, so it matches any numeric value.  

The zsh equivalent to the regex "+" is "##", so you could also use
"/var/tmp/exec.[0-9]##" (make sure EXTENDED_GLOB is set).
