Here's the MEL code that will allow you to select only the joints in a hierarchy for baking the keys.

// Begin copy
// Select the root joint only and execute this script

select -hi ; // selects the hierarchy
string $joints[] = `ls -sl -type joint` ; // puts the selected joints into an array

select -r $joints ; // select the array of joints
print (size($joints)) ; // print the total number of joints
