Unfortunately, it is not easy to fix this problem.
Because, proc.KernelModeTime and WorkingSetSize are VT_BSTR  OLE type.
And win32ole converts VT_BSTR object of OLE to String of Ruby.

In VBScript, proc.KernelModeTime and proc.WorkingSetsize
are VT_BSTR(vbString) type.

Set wmi = getObject("winmgmts:")
for each proc in wmi.InstancesOf("Win32_Process")
    WScript.Echo proc.Caption
    WScript.Echo VarType(proc.Caption) ' ==> 8:vbString
    WScript.Echo "============================"

    WScript.Echo proc.ParentProcessId
    WScript.Echo VarType(proc.ParentProcessId) ' ==> 3:vbLong
    WScript.Echo proc.SessionId
    WScript.Echo VarType(proc.SessionId) ' ==> 3:vbLong
    WScript.Echo "============================"

    WScript.Echo proc.KernelModeTime
    WScript.Echo VarType(proc.KernelModeTime) ' ==> 8:vbString
    WScript.Echo proc.WorkingSetSize
    WScript.Echo VarType(proc.WorkingSetSize) ' ==> 8:vbString
    exit for
next
