See section 7.3.5.2 of IEEE 1275.

$number    ( addr len -- true | n false )   Convert a string to a number

But aside from that, I'm not sure what the hesitation to use ascii
strings in drivers comes from. It's standard practice. Video drivers are
usually specified with device strings like "/pci at xx/display at 1:1040x1024"
or something like that, with the option argument being parsed at runtime
(often it's a straight string comparison, but sometimes it needs more
detailed parsing).
