This is invalid code, a illegal mixture of VRML97 and X3D:

#VRML V2.0 utf8
...
DEF s041e1630 Script{ # // line 1747 ungziped jerry2.wrl
...
exposedField SFNode PI1_sacroiliac USE PI1_sacroiliac # // line 1761 ungziped jerry2.wrl

But exposedField (or better "inputOutput") in scripts is only allowed in X3D,
but the file has a VRML97 header:

See 

http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/grammar.html

...
restrictedInterfaceDeclaration ::=
eventIn fieldType eventInId | 
eventOut fieldType eventOutId | 
field fieldType fieldId fieldValue ; 
...
Script { scriptBody } ;
...
scriptBody ::=

scriptBodyElement scriptBody | 
empty ; 
scriptBodyElement ::=

restrictedInterfaceDeclaration |

protoStatement ;

Next step: get a valid H-Anim avatar 8-)
